-
-<p>This release is known to be incompatible with prior versions of the client
-libraries. That is, the 2.0.0 or 2.0.1 version of the client libraries will not
-be able to communicate with a 2.1.0 or later installation of Accumulo, nor will
-the 2.1.0 or later version of the client libraries communicate with a 2.0.1 or
-earlier installation.</p>
-
-<h2 id="major-changes">Major Changes</h2>
-
-<h3 id="overhaul-of-table-compactions">Overhaul of Table Compactions</h3>
-
-<p>Significant changes were made to how Accumulo compacts files in this
release. See
-<a href="/docs/2.x/administration/compaction">compaction </a> for details,
below are some highlights.</p>
-
-<ul>
- <li>Multiple concurrent compactions per tablet on disjoint files is now
-supported. Previously only a single compaction could run on a tablet. This
-allows tablets that are running long compactions on large files to
-concurrently compact new smaller files that arrive.</li>
- <li>Multiple compaction thread pools per tablet server are now supported.
-Previously only a single thread pool existed within a tablet server for
-compactions. With a single thread pool, if all threads are working on long
-compactions it can starve quick compactions. Now compactions with little
-data can be processed by dedicated thread pools.</li>
- <li>Accumulo’s default algorithm for selecting files to compact was modified
to
-select the smallest set of files that meet the compaction ratio criteria
-instead of the largest set. This change makes tablets more aggressive about
-reducing their number files while still doing logarithmic compaction work.
-This change also enables efficiently compacting new small files that arrive
-during a long running compaction.</li>
- <li>Having dedicated compaction threads pools for tables is now supported
-through configuration. The default configuration for Accumulo sets up
-dedicated thread pools for compacting the Accumulo metadata table.</li>
- <li>Merging minor compactions were dropped. These were added to Accumulo to
-address the problem of new files arriving while a long running compaction
-was running. Merging minor compactions could cause O(N^2) compaction work.
-The new compaction changes in this release can satisfy this use case while
-doing a logarithmic amount of work.</li>
-</ul>
-
-<p>CompactionStrategy was deprecated in favor of new public APIs.
CompactionStrategy was never public API as it
-used internal types and one of these types <code class="language-plaintext
highlighter-rouge">FileRef</code> was removed in 2.1. Users who have written a
CompactionStrategy
-can replace <code class="language-plaintext highlighter-rouge">FileRef</code>
with its replacement internal type <code class="language-plaintext
highlighter-rouge">StoredTabletFile</code> but this is not recommended. Since
it is
-very likely that CompactionStrategy will be removed in a future release, any
work put into rewriting a CompactionStrategy
-will be lost. It is recommended that users implement CompactionSelector,
CompactionConfigurer, and CompactionPlanner instead. The new compaction
changes in 2.1 introduce new algorithms for optimally scheduling compactions
across multiple thread pools, configuring a deprecated compaction strategy may
result is missing out on the benefits of these new algorithms. See
-<a
href="https://static.javadoc.io/org.apache.accumulo/accumulo-tserver/2.0.1/org/apache/accumulo/tserver/compaction/CompactionStrategy.html";>javadoc</a>

-<h3 id="external-compactions-experimental">External Compactions
(experimental)</h3>
-
-<p>This release includes two new optional server components,
CompactionCoordinator and Compactor,
-that enables the user to run major compactions outside of the Tablet Server.

-over many tickets, see the GitHub <a

related issues. <a
href="https://github.com/apache/accumulo/issues/2096";>#2096</a></p>
-
-<h3 id="fixed-gc-metadata-hotspots">Fixed GC Metadata hotspots</h3>
-
-<p>Prior to this release, Accumulo stored GC file candidates in the metadata
table
-using rows of the form <code class="language-plaintext
highlighter-rouge">~del<URI></code>. This row schema lead to uneven load
on
-the metadata table and metadata tablets that were eventually never used. In <a
href="https://github.com/apache/accumulo/issues/1043";>#1043</a> <a
href="https://github.com/apache/accumulo/issues/1344";>#1344</a> the row format
was changed to <code class="language-plaintext
highlighter-rouge">~del<hash(URI)><URI></code> resulting in
-even load on the metadata table and even data spread in the tablets. After
-upgrading, there may still be splits in the metadata table using the old row
-format. These splits can be merged away as shown in the example below which
-starts off with splits generated from the old and new row schema. The old
-splits with the prefix <code class="language-plaintext
highlighter-rouge">~delhdfs</code> are merged away.</p>

-<h3 id="master-renamed-to-manager">Master Renamed to Manager</h3>
-
-<p>In order to support more inclusive language in our code, the Accumulo team
has
-renamed all references to the word “master” to “manager” (with the exception
-of deprecated classes and packages retained for compatibility). This change
-includes the master process, configuration properties with master in the name,
-utilities with master in the name, and packages/classes in the code base. Where
-these changes affect the public API, the deprecated “master” name will still be
-supported until at least Accumulo 3.0.</p>
-
-<blockquote>
- <p><strong>Important</strong>
- One particular change to be aware of is that certain state for the manager
- process is stored in ZooKeeper, previously in under a directory named
- <code class="language-plaintext highlighter-rouge">masters</code>. This
directory has been renamed to <code class="language-plaintext
highlighter-rouge">managers</code>, and the upgrade
- will happen automatically if you launch Accumulo using the provided scripts.
- However, if you do not use the built in scripts (e.g., accumulo-cluster or
- accumulo-service), then you will need to perform a one-time upgrade of the
- ZooKeeper state by executing the <code class="language-plaintext
highlighter-rouge">RenameMasterDirInZK</code> utility:</p>
- <div class="language-plaintext highlighter-rouge"><div
class="highlight"><pre class="highlight"><code> ${ACCUMULO_HOME}/bin/accumulo
org.apache.accumulo.manager.upgrade.RenameMasterDirInZK
-</code></pre></div> </div>
-</blockquote>
-
-<p>Some other specific examples of these changes include:</p>
-
-<ul>
- <li>All configuration properties starting with <code
class="language-plaintext highlighter-rouge">master.</code> have been renamed to
-start with <code class="language-plaintext highlighter-rouge">manager.</code>
instead. The <code class="language-plaintext highlighter-rouge">master.*</code>
property names in the site
-configuration file (or passed on the command-line) are converted internally
-to the new name, and a warning is printed. However, the old name can still be
-used until at least the 3.0 release of Accumulo. Any <code
class="language-plaintext highlighter-rouge">master.*</code> properties
-that have been set in ZooKeeper will be automatically converted to the new
-<code class="language-plaintext highlighter-rouge">manager.*</code> name when
Accumulo is upgraded. The old property names can still
-be used by the <code class="language-plaintext
highlighter-rouge">config</code> shell command or via the methods accessible via
-<code class="language-plaintext highlighter-rouge">AccumuloClient</code>, but
a warning will be generated when the old names are
-used. You are encouraged to update all references to <code
class="language-plaintext highlighter-rouge">master</code> in your site
-configuration files to <code class="language-plaintext
highlighter-rouge">manager</code> when installing Accumulo 2.1.</li>
- <li>The tablet balancers in the <code class="language-plaintext
highlighter-rouge">org.apache.accumulo.server.master.balancer</code>
-package have all been relocated to <code class="language-plaintext
highlighter-rouge">org.apache.accumulo.server.manager.balancer</code>.
-DefaultLoadBalancer has been also renamed to SimpleLoadBalancer along with
-the move. The default balancer has been updated from
-<code class="language-plaintext
highlighter-rouge">org.apache.accumulo.server.master.balancer.TableLoadBalancer</code>
to
-<code class="language-plaintext
highlighter-rouge">org.apache.accumulo.server.manager.balancer.TableLoadBalancer</code>,
and the
-default per-table balancer has been updated from
-<code class="language-plaintext
highlighter-rouge">org.apache.accumulo.server.master.balancer.DefaultLoadBalancer</code>
to
-<code class="language-plaintext
highlighter-rouge">org.apache.accumulo.server.manager.balancer.SimpleLoadBalancer</code>.
If you have
-customized the tablet balancer configuration, you are strongly encouraged to
-update your configuration to reference the updated balancer names. If you
-written a custom tablet balancer, it should be updated to implement the new
-interface <code class="language-plaintext
highlighter-rouge">org.apache.accumulo.server.manager.balancer.TabletBalancer</code>
-rather than extending the deprecated abstract
-<code class="language-plaintext
highlighter-rouge">org.apache.accumulo.server.master.balancer.TabletBalancer</code>.</li>
- <li>The configuration file <code class="language-plaintext
highlighter-rouge">masters</code> for identifying the manager host(s) has been
-deprecated. If this file is found, a warning will be printed. The replacement
-file <code class="language-plaintext highlighter-rouge">managers</code> should
be used (i.e., rename your masters file to managers)
-instead.</li>
- <li>The <code class="language-plaintext highlighter-rouge">master</code>
argument to the <code class="language-plaintext
highlighter-rouge">accumulo-service</code> script has been deprecated,
-and the replacement <code class="language-plaintext
highlighter-rouge">manager</code> argument should be used instead.</li>
- <li>The <code class="language-plaintext highlighter-rouge">-master</code>
argument to the <code class="language-plaintext
highlighter-rouge">org.apache.accumulo.server.util.ZooZap</code>
-utility has been deprecated and the replacement <code
class="language-plaintext highlighter-rouge">-manager</code> argument should be
-used instead.</li>
- <li>The <code class="language-plaintext
highlighter-rouge">GetMasterStats</code> utility has been renamed to <code
class="language-plaintext highlighter-rouge">GetManagerStats</code>.</li>
- <li><code class="language-plaintext
highlighter-rouge">org.apache.accumulo.master.state.SetGoalState</code> is
deprecated, and any custom
-scripts that invoke this utility should be updated to call
-<code class="language-plaintext
highlighter-rouge">org.apache.accumulo.manager.state.SetGoalState</code>
instead.</li>
- <li><code class="language-plaintext highlighter-rouge">masterMemory</code>
in <code class="language-plaintext
highlighter-rouge">minicluster.properties</code> has been deprecated and
-<code class="language-plaintext highlighter-rouge">managerMemory</code> should
be used instead in any <code class="language-plaintext
highlighter-rouge">minicluster.properties</code> files
-you have configured.</li>

-<h3 id="new-listtablets-shell-command">New listtablets shell command.</h3>
-
-<p>A new command was created for debugging called listtablets, that shows
detailed tablet information
-on a single line. This command aggregates data about a tablet such as status,
location, size,
-number of entries and HDFS directory name. It even shows the start and end
rows of tablets,
-displaying them in the same sorted order they are stored in the metadata. See
example command output below.

-<h3 id="new-utility-for-generating-splits">New Utility for generating
splits</h3>
-
-<p>A new command line utility was created to generate split points from 1 or
more rfiles. One or more HDFS directories can
-be given as well. The utility will iterate over all the files provided and
determine the proper split points
-based on either the size or number given. It uses Apache Datasketches to get
the split points from the data. <a

-<h3 id="new-max-tablets-option-in-bulk-import">New max tablets option in bulk
import</h3>
-
-<p>The property <code class="language-plaintext
highlighter-rouge">table.bulk.max.tablets</code> was created in new bulk import
technique. This property acts as a cluster performance
-failsafe to prevent a single ingested file from being distributed across too
much of a cluster. The value is enforced
-by the new bulk import technique and is the maximum number of tablets allowed
for one bulk import file. When this property
-is set, an error will be thrown when the value is exceeded during a bulk
import. <a href="https://github.com/apache/accumulo/issues/1614";>#1614</a></p>
-
-<h3 id="new-health-check-thread-in-tserver">New Health check Thread in
tserver</h3>
-
-<p>A new thread was added to the tablet server to periodically verify tablet
metadata. <a href="https://github.com/apache/accumulo/issues/2320";>#2320</a>
This thread also prints
-to the debug log how long it takes the tserver to scan the metadata table. The
property tserver.health.check.interval was
-added to control the frequency at which this health check takes place. <a

-<h3 id="new-ability-for-user-to-define-context-classloaders">New ability for

-
-<p>Deprecated the existing VFS ClassLoader for eventual removal and created a
new mechanism for users
-to load their own classloader implementations. The new VFS classloader and VFS
context classloaders
-are in a new <a
href="https://github.com/apache/accumulo-classloaders/tree/main/modules/vfs-class-loader";>repo</a>

in uncaught Exception/Error handling in server-side threads</h3>
-
-<p>Consolidated and normalized thread pool and thread creation. All threads
created through this code path
-will have an UncaughtExceptionHanlder attached to it that will log the fact
that the Thread encountered
-an uncaught Exception and is now dead. When an Error is encountered in a
server process, it will attempt
-to print a message to stderr then terminate the VM using Runtime.halt. On the
client side, the default
-UncaughtExceptionHandler will only log the Exception/Error in the client and
does not terminate the VM.
-Additionally, the user has the ability to set their own
UncaughtExceptionHandler implementation on the
-client. <a href="https://github.com/apache/accumulo/issues/1808";>#1808</a> <a

Performance improvements when deleting tables</h3>
-
-<ul>
- <li>Make delete table operations cancel user compactions <a
href="https://github.com/apache/accumulo/issues/2030";>#2030</a> <a
href="https://github.com/apache/accumulo/issues/2169";>#2169</a>.</li>
- <li>Prevent compactions from starting when delete table is called <a
href="https://github.com/apache/accumulo/issues/2182";>#2182</a> <a
href="https://github.com/apache/accumulo/issues/2240";>#2240</a>.</li>
- <li>Added check to not flush when table is being deleted <a
href="https://github.com/apache/accumulo/issues/1887";>#1887</a>.</li>
- <li>Added log message before waiting for deletes to finish <a
href="https://github.com/apache/accumulo/issues/1881";>#1881</a>.</li>
- <li>Added code to stop user flush if table is being deleted <a
href="https://github.com/apache/accumulo/issues/1931";>#1931</a></li>
-</ul>
-
-<h3 id="new-jshell-entry-point">New jshell entry point</h3>
-
-<p>Created new “jshell” convenience entry point <a
href="https://github.com/apache/accumulo/issues/1870";>#1870</a> <a
href="https://github.com/apache/accumulo/issues/1910";>#1910</a></p>
-
-<h3 id="new-monitor-pages--improvments">New Monitor Pages &
Improvments</h3>
-
-<p>A page was added to the Monitor that lists the active compactions and the
longest running
-active compaction. As an optimization, the page will only fetch data if a user
loads the
-page and will only do so a maximum of once a minute. The same optimization was
added for the Active Scans page,
-along with the addition of a “Fetched” column indicating when the data was
retrieved. A new page was also created
-for External Compactions that allows seeing the progress of compactions and
many details about ongoing compactions.

-<h3 id="new-tserver-scan-timeout-property">New tserver scan timeout
property</h3>
-
-<p>The new property <code class="language-plaintext
highlighter-rouge">tserver.scan.results.max.timeout</code> was added to allow
configuration of the timeout. A bug was
-discovered where tservers were running out of memory, partially due to this
timeout being so short. The default value
-is 1 second, but now it can be increased. It is the max time for the thrift
client handler to wait for scan results before
-timing out. <a href="https://github.com/apache/accumulo/issues/2599";>#2599</a>
