+ <title>Apache Accumulo 3.0.0</title>
+ <description><h2 id="about">About</h2>
+
+<p>Apache Accumulo 3.0.0 is a non-LTM major version release. While it
+primarily contains the 2.1 codebase, including all patches through
+2.1.2, it has also removed a substantial number of deprecated features
+and code, in an attempt to clean up several years of accrued technical
+debt, and lower the maintenance burden to make way for future
+improvements. It also contains a few other minor improvements.</p>
+
+<h2 id="notable-removals">Notable Removals</h2>
+
+<ul>
+ <li><a
href="https://github.com/apache/accumulo/issues/1328">#1328</a>
The FileSystem monitor has been removed and will no
+longer watch for problems with local file systems and self-terminate.
+System administrators are encouraged to use whatever systems health
+monitoring is appropriate for their deployments, rather than depend on
+Accumulo to monitor these.</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/2443">#2443</a>
The MapReduce APIs embedded in the accumulo-core module
+were removed. The separate <code class="language-plaintext
highlighter-rouge">accumulo-hadoop-mapreduce</code> jar is their
+replacement.</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3073">#3073</a>
The legacy Connector and Instance client classes were removed.
+The AccumuloClient is their replacement.</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3080">#3080</a>
The cross-data center replication feature was removed without
+replacement due to lack of being maintained, having numerous outstanding
+unfixed issues with no volunteer to maintain it since it was deprecated, and
+substantial code complexity. The built-in replication table it used for
+tracking replication metadata will be removed on upgrade.</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3114">#3114</a>,
<a
href="https://github.com/apache/accumulo/issues/3115">#3115</a>,
<a
href="https://github.com/apache/accumulo/issues/3116">#3116</a>,
<a
href="https://github.com/apache/accumulo/issues/3117">#3117</a>
Removed
+deprecated VolumeChooser, TabletBalancer, Constraint, and other APIs, in
+favor of their SPI replacements.</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3106">#3106</a>
Remove deprecated configuration properties (see 2.1 property
+documentation for which ones were deprecated)</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3112">#3112</a>
Remove CompactionStrategy class in favor of CompactionSelector
+and CompactionConfigurer.</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3160">#3160</a>
Remove upgrade code for versions prior to 2.1 (minimum version
+to upgrade from is now 2.1.</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3192">#3192</a>
Remove arguments to server processes, such as (<code
class="language-plaintext highlighter-rouge">-a</code>,
<code class="language-plaintext
highlighter-rouge">-g</code>,
+<code class="language-plaintext
highlighter-rouge">-q</code>, etc.) were removed in favor of
configuration properties that can be
+specified in the Accumulo configuration files or supplied on a per-process
+basis using the <code class="language-plaintext
highlighter-rouge">-o</code> argument. The provided cluster
management reference
+scripts were updated in <a
href="https://github.com/apache/accumulo/issues/3197">#3197</a>
to use the <code class="language-plaintext
highlighter-rouge">-o</code> method.</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3136">#3136</a>
Remove the built-in VFS classloader support. To use a custom
+classloader, users must now set the ContextClassLoaderFactory implementation
+in the properties. The default is now the
URLContextClassLoaderFactory.</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3318">#3318</a>
Remove the old bulk import implementation, replaced by the new
+bulk import API added <a
href="https://accumulo.apache.org/release/accumulo-2.0.0/#new-bulk-import-api">in
2.0.0</a>.</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3265">#3265</a>
Remove scan interpreter and scan formatter from the shell</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3361">#3361</a>
Remove all remaining references to the old “master” service
+(renamed to “manager”).</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3360">#3360</a>
Remove checks and code related to the old password hashing
+mechanism in Accumulo. This will discontinue warnings about users passwords
+that are still out of date. Instead, those outdated passwords will simply
+become invalid. If the user authenticated to Accumulo at any time prior to
+upgrading, their password will have been converted. So this only affects
+accounts that were never used with 2.1 at all. As mitigation, such users will
+be able to have their password reset by the root user. If the root user never
+authenticated (and neither had another admin user) while on 2.1 (very very
+unlikely), an administrator can reset the entire user database through the
+normal init step to reset security.</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3378">#3378</a>
Remove broken support for old map files. (RFiles have been in
+use for a long time, so this should not impact any users; if users had been
+trying to use map files, they would have found that they were broken
anyway)</li>
+</ul>
+
+<h2 id="notable-additions">Notable Additions</h2>
+
+<ul>
+ <li><a
href="https://github.com/apache/accumulo/issues/3088">#3088</a>
New methods were added to compaction-related APIs to share
+information about the current tablet being compacted to user code</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3107">#3107</a>
Decompose internal thrift services by function to make RPC
+functionality more modular by server instances</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3189">#3189</a>
Standardized server lock data structure in ZooKeeper</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3206">#3206</a>
Internal caches now use Caffeine instead of Guava’s Cache</li>
+ <li><a
href="https://github.com/apache/accumulo/issues/3161">#3161</a>,
<a
href="https://github.com/apache/accumulo/issues/3288">#3288</a>
The internal service (renamed from
+GarbageCollectionLogger to LowMemoryDetector) that was previously used only
+to report low memory in servers, was made configurable to allow pausing
+certain operations like scanning, minor compactions, or major compactions,
+when memory is low. See the server properties for <code
class="language-plaintext
highlighter-rouge">general.low.mem.*</code>.</li>

-
-<p>Accumulo 1.x assumes the use of the CMS garbage collector in its
build tests

-versions of Java, and the build flags for Java that supported configuring the
-CMS garbage collector now cause errors if attempted to be used with Java 15 or
-later.</p>
-
-<p>Therefore, a change was made in 1.10.1’s build to fail fast if
attempting to
-build with JDK 15 or later (using JDK 11 or later was already a build
-requirement).</p>
-
-<p>If you need to build on JDK 15 or later, and intend to skip tests and
don’t
-intend to use minicluster, you can bypass this build constraint by building
-with <code class="language-plaintext

workaround.</p>

- <title>Apache Accumulo 1.10.0</title>
- <description><h2 id="about">About</h2>
-
-<p>Apache Accumulo 1.10.0 is a continuation of the 1.x release line, and
is
-essentially the next maintenance release of 1.8/1.9, following the 1.9.3
-version with some small additional internal improvements. Earlier 1.x versions
-are now superseded by this maintenance release, and will no longer be
-maintained.</p>
-
-<p>The <a
href="https://semver.org/spec/v2.0.0.html">semver</a> minor
version number increase (1.9 to 1.10) signals that this
-release is backwards compatible with previous minor releases (1.8 and 1.9).
-Rather than API additions, the primary reason for this minor version increase
-is due to the decision to make Java 8 the minimum supported Java version (see
-below for more).</p>
-
-<p>This release contains contributions from more than 13 contributors
from the
-Apace Accumulo community in over 80 commits and 16 months of work since the
-1.9.3 release. These release notes are highlights of those changes. The full
-detailed changes can be seen in the git history. If anything is missing from
-this list, please <a href="/contact-us">contact</a> us
to have it included.</p>
-
-<p>According to the <a
href="/contributor/versioning#LTM">Long Term Maintenance
(LTM)</a> strategy, the intent is to
-maintain the 1.10 release line with critical bug and security fixes until one
-year after the next LTM version is released. However, this is anticipated to be
-the final 1.x legacy release, so it is not expected to receive any new features
-or significant non-critical updates, so users wanting new features should plan
-to upgrade to a 2.x release, where new feature development is still being
done.</p>
-
-<p>Users of 1.9.3 or earlier are urged to upgrade to 1.10.0 as soon as
it is
-available, as this is a continuation of the 1.9 maintenance line. and to
-consider migrating to a 2.x version when a suitable one becomes available.
-Accumulo 2.0.0 is currently available, and 2.1.0 is anticipated to be the next
-LTM release. If you would like to start preparing for 2.1.0 now, one way to do
-this is to start building and testing the next version of your software against
-Accumulo 2.0.0 because all 2.x releases should be backwards compatible with
-2.0.0, following <a
href="https://semver.org/spec/v2.0.0.html">semantic
versioning</a>.</p>

-<h2 id="minimum-requirements">Minimum Requirements</h2>
-
-<p>The versions mentioned here are a guide only. It is not expected that
our
-convenience binary tarball will work out-of-the-box with your particular
-environment, and some responsibility is placed on users to properly configure
-Accumulo, or even patch and rebuild it from source, for their particular
-environment.</p>
-
-<p>Please <a href="/contact-us">contact</a> us or
file a <a href="https://github.com/apache/accumulo/issues">bug
report</a> if you have trouble with a
-specific version or wish to seek tips. Be prepared to provide details of the
-problems you encounter, as well as perform some troubleshooting steps of your
-own, in order to get the best response.</p>
-
-<h3 id="java-8">Java 8</h3>
-
-<p>Java 8 is now the minimum supported Java version, and it is designed
to work on
-Java 11, as well. To build the project from source, Java 11 or later is
-required. Please <a href="/contact-us">contact</a> us if

-<h3 id="hadoop-2-or-3">Hadoop 2 or 3</h3>
-
-<p>This release has been built using Hadoop 2.6.5, and is expected to
work with
-any Hadoop version 2.6.5 or later. It has also been tested with 3.0.3, and is
-expected to work with Hadoop 3.0 versions as well. Hadoop 3.1.3, 3.2.1, and
-3.3.0 have also been tested with this version, and are known to work (with at
-least basic functionality) with some class path modifications (specifically,
-using Guava 27.0-jre instead of the provided 14.0 version).</p>
-
-<p>Particular class path pain points are known to be guava, commons-io,
-commons-vfs2, and possibly other commons libraries.</p>
-
-<h3 id="zookeeper">ZooKeeper</h3>
-
-<p>This release has been built agains ZooKeeper 3.4.14, the latest 3.4
release. It
-is known to work against 3.5 and 3.6 versions as well, when configured
-properly.</p>

class could not be loaded,
-which failed the minor compaction thread. Once the minor compaction thread is
dead, it will prevent future minor compactions from starting, subsequently
preventing the tablet from being closed normally. The fixes here
-include catching a broader range of exceptions in the minor compaction thread
in an attempt to save it
-from dying and initiating a minor compaction before closing the compactable
object in the tablet.</p>

monitor will no longer stop the TabletServer</h3>
+<p>Apache Accumulo 3.0.0 is a non-LTM major version release. While it
+primarily contains the 2.1 codebase, including all patches through
+2.1.2, it has also removed a substantial number of deprecated features
+and code, in an attempt to clean up several years of accrued technical
+debt, and lower the maintenance burden to make way for future
+improvements. It also contains a few other minor improvements.</p>
-<p>In <a href="https://github.com/apache/accumulo/issues/1328";>#1328</a> the
<code class="language-plaintext highlighter-rouge">tserver.monitor.fs</code>
property has been marked as deprecated
-and the background thread in the TabletServer was modified to <em>not</em>
halt the TabletServer
-when one of the local disks becomes read-only.</p>
-
-<h3
id="garbagecollectionlogger-renamed-to-lowmemorydetector-is-no-longer-passive">GarbageCollectionLogger
renamed to LowMemoryDetector, is no longer passive</h3>
-
-<p>The GarbageCollectionLogger would run in a Thread in the server components
every 5 seconds
-and print a message to the log when the amount of free memory was less than 5%
of the heap.
-<a href="https://github.com/apache/accumulo/issues/3161";>#3161</a> renamed the
class to LowMemoryDetector, adds new properties for the threshold,
-interval, and passivity. When operating in a passive mode, the
LowMemoryDetector will log a
-message just like its predecessor. See the new GENERAL_LOW_MEM_*_PROTECTION
properties for a
-description of the behavior change when these properties are enabled. <a
href="https://github.com/apache/accumulo/issues/3288";>#3288</a> added a
-new metric, accumulo.detected.low.memory, that reports a value of 1 when the
server is low on
-memory.</p>

MapReduce APIs, deprecated in 2.0.0, were removed.</li>
+ <li><a href="https://github.com/apache/accumulo/issues/1328";>#1328</a> The
FileSystem monitor has been removed and will no
+longer watch for problems with local file systems and self-terminate.
+System administrators are encouraged to use whatever systems health
+monitoring is appropriate for their deployments, rather than depend on
+Accumulo to monitor these.</li>
+ <li><a href="https://github.com/apache/accumulo/issues/2443";>#2443</a> The
MapReduce APIs embedded in the accumulo-core module
+were removed. The separate <code class="language-plaintext
highlighter-rouge">accumulo-hadoop-mapreduce</code> jar is their
+replacement.</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3073";>#3073</a> The
legacy Connector and Instance client classes were removed.
+The AccumuloClient is their replacement.</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3080";>#3080</a> The
cross-data center replication feature was removed without
+replacement due to lack of being maintained, having numerous outstanding
+unfixed issues with no volunteer to maintain it since it was deprecated, and
+substantial code complexity. The built-in replication table it used for
+tracking replication metadata will be removed on upgrade.</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3114";>#3114</a>, <a

Remove deprecated configuration properties (see 2.1 property
+documentation for which ones were deprecated)</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3112";>#3112</a>
Remove CompactionStrategy class in favor of CompactionSelector
+and CompactionConfigurer.</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3160";>#3160</a>
Remove upgrade code for versions prior to 2.1 (minimum version
+to upgrade from is now 2.1.</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3192";>#3192</a>
Remove arguments to server processes, such as (<code class="language-plaintext
highlighter-rouge">-a</code>, <code class="language-plaintext
highlighter-rouge">-g</code>,
+<code class="language-plaintext highlighter-rouge">-q</code>, etc.) were
removed in favor of configuration properties that can be
+specified in the Accumulo configuration files or supplied on a per-process
+basis using the <code class="language-plaintext highlighter-rouge">-o</code>
argument. The provided cluster management reference
+scripts were updated in <a
href="https://github.com/apache/accumulo/issues/3197";>#3197</a> to use the
<code class="language-plaintext highlighter-rouge">-o</code> method.</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3136";>#3136</a>
Remove the built-in VFS classloader support. To use a custom
+classloader, users must now set the ContextClassLoaderFactory implementation
+in the properties. The default is now the URLContextClassLoaderFactory.</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3318";>#3318</a>
Remove the old bulk import implementation, replaced by the new
+bulk import API added <a
href="https://accumulo.apache.org/release/accumulo-2.0.0/#new-bulk-import-api";>in
2.0.0</a>.</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3265";>#3265</a>
Remove scan interpreter and scan formatter from the shell</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3361";>#3361</a>
Remove all remaining references to the old “master” service
+(renamed to “manager”).</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3360";>#3360</a>
Remove checks and code related to the old password hashing
+mechanism in Accumulo. This will discontinue warnings about users passwords
+that are still out of date. Instead, those outdated passwords will simply
+become invalid. If the user authenticated to Accumulo at any time prior to
+upgrading, their password will have been converted. So this only affects
+accounts that were never used with 2.1 at all. As mitigation, such users will
+be able to have their password reset by the root user. If the root user never
+authenticated (and neither had another admin user) while on 2.1 (very very
+unlikely), an administrator can reset the entire user database through the
+normal init step to reset security.</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3378";>#3378</a>
Remove broken support for old map files. (RFiles have been in
+use for a long time, so this should not impact any users; if users had been
+trying to use map files, they would have found that they were broken
anyway)</li>
</ul>
-<p>where applicable. Removed tserver TLevel logging class.</p>
+<h2 id="notable-additions">Notable Additions</h2>
+
<ul>
- <li><a
href="https://issues.apache.org/jira/browse/ACCUMULO-1787";>ACCUMULO-1787</a> -
Two tier compaction strategy. Support compacting small files with snappy and
large files with gzip.</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3088";>#3088</a> New
methods were added to compaction-related APIs to share
+information about the current tablet being compacted to user code</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3107";>#3107</a>
Decompose internal thrift services by function to make RPC
+functionality more modular by server instances</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3189";>#3189</a>
Standardized server lock data structure in ZooKeeper</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3206";>#3206</a>
Internal caches now use Caffeine instead of Guava’s Cache</li>
+ <li><a href="https://github.com/apache/accumulo/issues/3161";>#3161</a>, <a
href="https://github.com/apache/accumulo/issues/3288";>#3288</a> The internal
service (renamed from
+GarbageCollectionLogger to LowMemoryDetector) that was previously used only
+to report low memory in servers, was made configurable to allow pausing
+certain operations like scanning, minor compactions, or major compactions,
+when memory is low. See the server properties for <code
class="language-plaintext highlighter-rouge">general.low.mem.*</code>.</li>
