+<h1>Dynamic Interpreter Loading using REST API</h1>
+
+<div id="toc"></div>
+
+<p>Apache Zeppelin provides pluggable interpreter architecture which results
in a wide and variety of the supported backend system. In this section, we will
introduce <strong>Dynamic interpreter loading</strong> using <strong>REST
API</strong>. This concept actually comes from <a
href="https://cwiki.apache.org/confluence/display/ZEPPELIN/Helium+proposal";>Zeppelin
Helium Proposal</a>.
+Before we start, if you are not familiar with the concept of <strong>Zeppelin
interpreter</strong>, you can check out <a href="./overview.html">Overview:
Zeppelin Interpreter</a> first.</p>
+
+<h2>Overview</h2>
+
+<p>In the past, Zeppelin was loading interpreter binaries from
<code>/interpreter/[interpreter_name]</code> directory. They were configured by
<code>zeppelin.interpreters</code> property in
<code>conf/zeppelin-site.xml</code> or <code>ZEPPELIN_INTERPRETERS</code> env
variables in <code>conf/zeppelin-env.sh</code>. They were loaded on Zeppelin
server startup and stayed alive until the server was stopped.
+In order to simplify using 3rd party interpreters, we changed this way to
<strong>dynamically</strong> load interpreters from <strong>Maven
Repository</strong> using <strong>REST API</strong>. Hopefully, the picture
below will help you to understand the process.
+<center><img
src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/zeppelin_user.png"
height="85%" width="85%"></center></p>
+
+<h2>Load & Unload Interpreters Using REST API</h2>
+
+<h3>Load</h3>
+
+<p>You can <strong>load</strong> interpreters located in Maven repository
using REST API, like this:</p>
+
+<p>(Maybe, you are unfamiliar with <code>[interpreter_group_name]</code> or
<code>[interpreter_name]</code>. If so, please checkout <a
href="./overview.html">Overview: Zeppelin Interpreter</a> again.)</p>
+<div class="highlight"><pre><code class="language-text"
data-lang="text"><span></span>http://[zeppelin-server]:[zeppelin-port]/api/interpreter/load/[interpreter_group_name]/[interpreter_name]
+</code></pre></div>
+<p>The Restful method will be <code><strong>POST</strong></code>. And the
parameters you need are:</p>
+
+<ol>
+<li><p><strong>Artifact:</strong> Maven artifact ( groupId:artifactId:version
) </p></li>
+<li><p><strong>Class Name:</strong> Package name + Interpreter class
name</p></li>
+<li><p><strong>Repository ( optional ):</strong> Additional maven repository
address</p></li>
+</ol>
+
+<p>For example, if you want to load <code>markdown</code> interpreter to your
Zeppelin, the parameters and URL you need may look like:</p>
+<div class="highlight"><pre><code class="language-text"
data-lang="text"><span></span>http://127.0.0.1:8080/api/interpreter/load/md/markdown
+</code></pre></div><div class="highlight"><pre><code class="language-json"
data-lang="json"><span></span><span class="p">{</span>
+ <span class="nt">"artifact"</span><span class="p">:</span> <span
class="s2">"org.apache.zeppelin:zeppelin-markdown:0.6.0-SNAPSHOT"</span><span
class="p">,</span>
+ <span class="nt">"className"</span><span class="p">:</span> <span
class="s2">"org.apache.zeppelin.markdown.Markdown"</span><span
class="p">,</span>
+ <span class="nt">"repository"</span><span class="p">:</span> <span
class="p">{</span>
+ <span class="nt">"url"</span><span class="p">:</span> <span
class="s2">"http://dl.bintray.com/spark-packages/maven"</span><span
class="p">,</span>
+ <span class="nt">"snapshot"</span><span class="p">:</span> <span
class="kc">false</span>
+ <span class="p">}</span>
+<span class="p">}</span>
+</code></pre></div>
+<p>The meaning of each parameters is: </p>
+
+<ol>
+<li><strong>Artifact</strong></li>
+<li>groupId: org.apache.zeppelin</li>
+<li>artifactId: zeppelin-markdown</li>
+<li><p>version: 0.6.0-SNAPSHOT</p></li>
+<li><p><strong>Class Name</strong></p></li>
+<li><p>Package Name: org.apache.zeppelin</p></li>
+<li><p>Interpreter Class Name: markdown.Markdown</p></li>
+<li><p><strong>Repository ( optional )</strong></p></li>
+<li><p>Url: http://dl.bintray.com/spark-packages/maven</p></li>
+<li><p>Snapshot: false</p></li>
+</ol>
+
+<blockquote>
+<p><b>Please note: </b>The interpreters you downloaded need to be
<strong>reload</strong>, when your Zeppelin server is down. </p>
+</blockquote>
+
+<h3>Unload</h3>
+
+<p>If you want to <strong>unload</strong> the interpreters using REST API, </p>
+<div class="highlight"><pre><code class="language-text"
data-lang="text"><span></span>http://[zeppelin-server]:[zeppelin-port]/api/interpreter/unload/[interpreter_group_name]/[interpreter_name]
+</code></pre></div>
+<p>In this case, the Restful method will be
<code><strong>DELETE</strong></code>.</p>
+
+<p><br/></p>
+
+<h2>What is the next step after Loading ?</h2>
+
+<h3>Q1. Where is the location of interpreters you downloaded ?</h3>
+
+<p>Actually, the answer about this question is in the above picture. Once the
REST API is called, the <code>.jar</code> files of interpreters you get are
saved under <code>ZEPPELIN_HOME/local-repo</code> first. Then, they will be
copied to <code>ZEPPELIN_HOME/interpreter</code> directory. So, please checkout
your <code>ZEPPELIN_HOME/interpreter</code>.</p>
+
+<h3>Q2. Then, how can I use this interpreter ?</h3>
+
+<p>After loading an interpreter, you can use it by creating and configuring it
in Zeppelin's <strong>Interpreter tab</strong>.</p>
+
+<p>Oh, you don't need to restart your Zeppelin server. Because it is
<strong>Dynamic Loading</strong>, you can configure and load it <strong>at
runtime</strong> !</p>
+
+<ol>
+<li><p>After Zeppelin server up, browse Zeppelin home and click
<strong>Interpreter tab</strong>.

+<h1>Interpreter Execution Hooks (Experimental)</h1>
+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p>Apache Zeppelin allows for users to specify additional code to be executed
by an interpreter at pre and post-paragraph code execution.
+This is primarily useful if you need to run the same set of code for all of
the paragraphs within your notebook at specific times.
+Currently, this feature is only available for the spark and pyspark
interpreters.
+To specify your hook code, you may use <code>z.registerHook()</code>.
+For example, enter the following into one paragraph:</p>
+<div class="highlight"><pre><code class="language-python"
data-lang="python"><span></span><span class="o">%</span><span
class="n">pyspark</span>
+<span class="n">z</span><span class="o">.</span><span
class="n">registerHook</span><span class="p">(</span><span
class="s2">"post_exec"</span><span class="p">,</span> <span
class="s2">"print 'This code should be executed before the parapgraph
code!'"</span><span class="p">)</span>
+<span class="n">z</span><span class="o">.</span><span
class="n">registerHook</span><span class="p">(</span><span
class="s2">"pre_exec"</span><span class="p">,</span> <span
class="s2">"print 'This code should be executed after the paragraph
code!'"</span><span class="p">)</span>
+</code></pre></div>
+<p>These calls will not take into effect until the next time you run a
paragraph. </p>
+
+<p>In another paragraph, enter</p>
+<div class="highlight"><pre><code class="language-python"
data-lang="python"><span></span><span class="o">%</span><span
class="n">pyspark</span>
+<span class="k">print</span> <span class="s2">"This code should be
entered into the paragraph by the user!"</span>
+</code></pre></div>
+<p>The output should be:</p>
+<div class="highlight"><pre><code class="language-text"
data-lang="text"><span></span>This code should be executed before the paragraph
code!
+This code should be entered into the paragraph by the user!
+This code should be executed after the paragraph code!
+</code></pre></div>
+<p>If you ever need to know the hook code, use <code>z.getHook()</code>:</p>
+<div class="highlight"><pre><code class="language-python"
data-lang="python"><span></span><span class="o">%</span><span
class="n">pyspark</span>
+<span class="k">print</span> <span class="n">z</span><span
class="o">.</span><span class="n">getHook</span><span class="p">(</span><span
class="s2">"post_exec"</span><span class="p">)</span>
+
+<span class="k">print</span> <span class="s1">'This code should be
executed after the paragraph code!'</span>
+</code></pre></div>
+<p>Any call to <code>z.registerHook()</code> will automatically overwrite what
was previously registered.
+To completely unregister a hook event, use
<code>z.unregisterHook(eventCode)</code>.
+Currently only <code>"post_exec"</code> and
<code>"pre_exec"</code> are valid event codes for the Zeppelin Hook
Registry system.</p>
+
+<p>Finally, the hook registry is internally shared by other interpreters in
the same group.
+This would allow for hook code for one interpreter REPL to be set by another
as follows:</p>
+<div class="highlight"><pre><code class="language-scala"
data-lang="scala"><span></span><span class="o">%</span><span
class="n">spark</span>
+<span class="n">z</span><span class="o">.</span><span
class="n">unregisterHook</span><span class="o">(</span><span
class="s">"post_exec"</span><span class="o">,</span> <span
class="s">"pyspark"</span><span class="o">)</span>
+</code></pre></div>
+<p>The API is identical for both the spark (scala) and pyspark (python)
implementations.</p>
+
+<h3>Caveats</h3>
+
+<p>Calls to <code>z.registerHook("pre_exec", ...)</code> should be
made with care. If there are errors in your specified hook code, this will
cause the interpreter REPL to become unable to execute any code pass the
pre-execute stage making it impossible for direct calls to
<code>z.unregisterHook()</code> to take into effect. Current workarounds
include calling <code>z.unregisterHook()</code> from a different interpreter
REPL in the same interpreter group (see above) or manually restarting the
interpreter group in the UI. </p>

+<h1>Installing Interpreters</h1>
+
+<div id="toc"></div>
+
+<p>Apache Zeppelin provides <strong>Interpreter Installation</strong>
mechanism for whom downloaded Zeppelin <code>netinst</code> binary package, or
just want to install another 3rd party interpreters.</p>
+
+<h2>Community managed interpreters</h2>
+
+<p>Apache Zeppelin provides several interpreters as <a
href="#available-community-managed-interpreters">community managed
interpreters</a>.
+If you downloaded <code>netinst</code> binary package, you need to install by
using below commands.</p>
+
+<h4>Install all community managed interpreters</h4>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>./bin/install-interpreter.sh --all
+</code></pre></div>
+<h4>Install specific interpreters</h4>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>./bin/install-interpreter.sh --name
md,shell,jdbc,python
+</code></pre></div>
+<p>You can get full list of community managed interpreters by running</p>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>./bin/install-interpreter.sh --list
+</code></pre></div>
+<h4>Install interpreter built with Scala 2.10</h4>
+
+<p>Zeppelin support both Scala 2.10 and 2.11 for several interpreters as
below:</p>
+
+<table class="table-configuration">
+ <tr>
+ <th>Name</th>
+ <th>Maven Artifact for Scala 2.10</th>
+ <th>Maven Artifact for Scala 2.11</th>
+ </tr>
+ <tr>
+ <td>cassandra</td>
+ <td>org.apache.zeppelin:zeppelin-cassandra_2.10:0.8.0</td>
+ <td>org.apache.zeppelin:zeppelin-cassandra_2.11:0.8.0</td>
+ </tr>
+ <tr>
+ <td>flink</td>
+ <td>org.apache.zeppelin:zeppelin-flink_2.10:0.8.0</td>
+ <td>org.apache.zeppelin:zeppelin-flink_2.11:0.8.0</td>
+ </tr>
+ <tr>
+ <td>ignite</td>
+ <td>org.apache.zeppelin:zeppelin-ignite_2.10:0.8.0</td>
+ <td>org.apache.zeppelin:zeppelin-ignite_2.11:0.8.0</td>
+ </tr>
+ <tr>
+ <td>scio</td>
+ <td>org.apache.zeppelin:zeppelin-scio_2.10:0.8.0</td>
+ <td>org.apache.zeppelin:zeppelin-scio_2.11:0.8.0</td>
+ </tr>
+</table>
+
+<p>If you install one of these interpreters only with <code>--name</code>
option, installer will download interpreter built with Scala 2.11 by default.
If you want to specify Scala version, you will need to add
<code>--artifact</code> option. Here is the example of installing flink
interpreter built with Scala 2.10.</p>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>./bin/install-interpreter.sh --name flink
--artifact org.apache.zeppelin:zeppelin-flink_2.10:0.8.0
+</code></pre></div>
+<h4>Spark interpreter for scala 2.10 and 2.11</h4>
+
+<p>Starting from Zeppelin 0.8.0, Zeppelin support both scala 2.10 and 2.11 in
one zeppelin instance. You don't need to install different scala specific
interpreter for spark.
+It would pick up the right scala specific interpreter for the spark
distribution where <code>SPARK_HOME</code> point to.</p>
+
+<p>Here's the command to install spark interpreter</p>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>rm -rf ./interpreter/spark
+./bin/install-interpreter.sh --name spark --artifact
org.apache.zeppelin:spark-interpreter:0.8.0
+</code></pre></div>
+<p>Once you have installed interpreters, you need to restart Zeppelin. And
then <a href="./overview.html#what-is-zeppelin-interpreter">create interpreter
setting</a> and <a
href="./overview.html#what-is-zeppelin-interpreter-setting">bind it with your
notebook</a>.</p>
+
+<h2>3rd party interpreters</h2>
+
+<p>You can also install 3rd party interpreters located in the maven repository
by using below commands.</p>
+
+<h4>Install 3rd party interpreters</h4>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>./bin/install-interpreter.sh --name interpreter1
--artifact groupId1:artifact1:version1
+</code></pre></div>
+<p>The above command will download maven artifact
<code>groupId1:artifact1:version1</code> and all of its transitive dependencies
into <code>interpreter/interpreter1</code> directory.</p>
+
+<p>After restart Zeppelin, then <a
href="./overview.html#what-is-zeppelin-interpreter">create interpreter
setting</a> and <a href="./overview.html#what-is-interpreter-setting">bind it
with your note</a>.</p>
+
+<h4>Install multiple 3rd party interpreters at once</h4>
+<div class="highlight"><pre><code class="language-bash"
data-lang="bash"><span></span>./bin/install-interpreter.sh --name
interpreter1,interpreter2 --artifact
groupId1:artifact1:version1,groupId2:artifact2:version2
+</code></pre></div>
+<p><code>--name</code> and <code>--artifact</code> arguments will recieve
comma separated list.</p>
+
+<h2>Available community managed interpreters</h2>
+
+<p>You can also find the below community managed interpreter list in
<code>conf/interpreter-list</code> file.
