+<h1>Spark Interpreter for Apache Zeppelin</h1>
+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p><a href="http://spark.apache.org">Apache Spark</a> is a fast and general-purpose cluster computing system.
+It provides high-level APIs in Java, Scala, Python and R, and an optimized engine that supports general execution graphs.
+Apache Spark is supported in Zeppelin with Spark interpreter group which consists of below five interpreters.</p>

+
+<p>Without any configuration, Spark interpreter works out of box in local mode. But if you want to connect to your Spark cluster, you'll need to follow below two simple steps.</p>
+
+<h3>1. Export SPARK_HOME</h3>
+
+<p>In <code>conf/zeppelin-env.sh</code>, export <code>SPARK_HOME</code> environment variable with your Spark installation path.</p>
+
+<p>For example,</p>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash"><span class="nb">export </span><span class="nv">SPARK_HOME</span><span class="o">=</span>/usr/lib/spark
+</code></pre></div>
+<p>You can optionally set more environment variables</p>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash"><span class="c"># set hadoop conf dir</span>
+<span class="nb">export </span><span class="nv">HADOOP_CONF_DIR</span><span class="o">=</span>/usr/lib/hadoop
+
+<span class="c"># set options to pass spark-submit command</span>
+<span class="nb">export </span><span class="nv">SPARK_SUBMIT_OPTIONS</span><span class="o">=</span><span class="s2">"--packages com.databricks:spark-csv_2.10:1.2.0"</span>
+
+<span class="c"># extra classpath. e.g. set classpath for hive-site.xml</span>
+<span class="nb">export </span><span class="nv">ZEPPELIN_INTP_CLASSPATH_OVERRIDES</span><span class="o">=</span>/etc/hive/conf
+</code></pre></div>
+<p>For Windows, ensure you have <code>winutils.exe</code> in <code>%HADOOP_HOME%\bin</code>. Please see <a href="https://wiki.apache.org/hadoop/WindowsProblems">Problems running Hadoop on Windows</a> for the details.</p>
+
+<h3>2. Set master in Interpreter menu</h3>
+
+<p>After start Zeppelin, go to <strong>Interpreter</strong> menu and edit <strong>master</strong> property in your Spark interpreter setting. The value may vary depending on your Spark cluster deployment type.</p>
+
+<p>For example,</p>
+
+<ul>
+<li><strong>local[*]</strong> in local mode</li>
+<li><strong>spark://master:7077</strong> in standalone cluster</li>
+<li><strong>yarn-client</strong> in Yarn client mode</li>
+<li><strong>yarn-cluster</strong> in Yarn cluster mode</li>
+<li><strong>mesos://host:5050</strong> in Mesos cluster</li>
+</ul>
+
+<p>That's it. Zeppelin will work with any version of Spark and any deployment type without rebuilding Zeppelin in this way.
+For the further information about Spark & Zeppelin version compatibility, please refer to "Available Interpreters" section in <a href="https://zeppelin.apache.org/download.html">Zeppelin download page</a>.</p>
+
+<blockquote>
+<p>Note that without exporting <code>SPARK_HOME</code>, it's running in local mode with included version of Spark. The included version may vary depending on the build profile.</p>
+</blockquote>
+
+<h3>3. Yarn mode</h3>
+
+<p>Zeppelin support both yarn client and yarn cluster mode (yarn cluster mode is supported from 0.8.0). For yarn mode, you must specify <code>SPARK_HOME</code> & <code>HADOOP_CONF_DIR</code>.
+You can either specify them in <code>zeppelin-env.sh</code>, or in interpreter setting page. Specifying them in <code>zeppelin-env.sh</code> means you can use only one version of <code>spark</code> & <code>hadoop</code>. Specifying them
+in interpreter setting page means you can use multiple versions of <code>spark</code> & <code>hadoop</code> in one zeppelin instance.</p>
+
+<h3>4. New Version of SparkInterpreter</h3>
+
+<p>There's one new version of SparkInterpreter with better spark support and code completion starting from Zeppelin 0.8.0. We enable it by default, but user can still use the old version of SparkInterpreter by setting <code>zeppelin.spark.useNew</code> as <code>false</code> in its interpreter setting.</p>
+
+<h2>SparkContext, SQLContext, SparkSession, ZeppelinContext</h2>
+
+<p>SparkContext, SQLContext and ZeppelinContext are automatically created and exposed as variable names <code>sc</code>, <code>sqlContext</code> and <code>z</code>, respectively, in Scala, Python and R environments.
+Staring from 0.6.1 SparkSession is available as variable <code>spark</code> when you are using Spark 2.x.</p>
+
+<blockquote>
+<p>Note that Scala/Python/R environment shares the same SparkContext, SQLContext and ZeppelinContext instance.</p>
+</blockquote>

+
+<h3>How to pass property to SparkConf</h3>
+
+<p>There're 2 kinds of properties that would be passed to SparkConf</p>
+
+<ul>
+<li>Standard spark property (prefix with <code>spark.</code>). e.g. <code>spark.executor.memory</code> will be passed to <code>SparkConf</code></li>
+<li>Non-standard spark property (prefix with <code>zeppelin.spark.</code>). e.g. <code>zeppelin.spark.property_1</code>, <code>property_1</code> will be passed to <code>SparkConf</code></li>
+</ul>
+
+<h2>Dependency Management</h2>
+
+<p>There are two ways to load external libraries in Spark interpreter. First is using interpreter setting menu and second is loading Spark properties.</p>
+
+<h3>1. Setting Dependencies via Interpreter Setting</h3>
+
+<p>Please see <a href="../usage/interpreter/dependency_management.html">Dependency Management</a> for the details.</p>
+
+<h3>2. Loading Spark Properties</h3>
+
+<p>Once <code>SPARK_HOME</code> is set in <code>conf/zeppelin-env.sh</code>, Zeppelin uses <code>spark-submit</code> as spark interpreter runner. <code>spark-submit</code> supports two ways to load configurations.
+The first is command line options such as --master and Zeppelin can pass these options to <code>spark-submit</code> by exporting <code>SPARK_SUBMIT_OPTIONS</code> in <code>conf/zeppelin-env.sh</code>. Second is reading configuration options from <code>SPARK_HOME/conf/spark-defaults.conf</code>. Spark properties that user can set to distribute libraries are:</p>
+
+<table class="table-configuration">
+ <tr>
+ <th>spark-defaults.conf</th>
+ <th>SPARK_SUBMIT_OPTIONS</th>
+ <th>Description</th>
+ </tr>
+ <tr>
+ <td>spark.jars</td>
+ <td>--jars</td>
+ <td>Comma-separated list of local jars to include on the driver and executor classpaths.</td>
+ </tr>
+ <tr>
+ <td>spark.jars.packages</td>
+ <td>--packages</td>
+ <td>Comma-separated list of maven coordinates of jars to include on the driver and executor classpaths. Will search the local maven repo, then maven central and any additional remote repositories given by --repositories. The format for the coordinates should be <code>groupId:artifactId:version</code>.</td>
+ </tr>
+ <tr>
+ <td>spark.files</td>
+ <td>--files</td>
+ <td>Comma-separated list of files to be placed in the working directory of each executor.</td>
+ </tr>
+</table>
+
+<p>Here are few examples:</p>
+
+<ul>
+<li><p><code>SPARK_SUBMIT_OPTIONS</code> in <code>conf/zeppelin-env.sh</code></p>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash"><span class="nb">export </span><span class="nv">SPARK_SUBMIT_OPTIONS</span><span class="o">=</span><span class="s2">"--packages com.databricks:spark-csv_2.10:1.2.0 --jars /path/mylib1.jar,/path/mylib2.jar --files /path/mylib1.py,/path/mylib2.zip,/path/mylib3.egg"</span>
+</code></pre></div></li>
+<li><p><code>SPARK_HOME/conf/spark-defaults.conf</code></p>
+<div class="highlight"><pre><code class="text language-text" data-lang="text">spark.jars /path/mylib1.jar,/path/mylib2.jar
+spark.jars.packages com.databricks:spark-csv_2.10:1.2.0
+spark.files /path/mylib1.py,/path/mylib2.egg,/path/mylib3.zip
+</code></pre></div></li>
+</ul>
+
+<h3>3. Dynamic Dependency Loading via %spark.dep interpreter</h3>
+
+<blockquote>
+<p>Note: <code>%spark.dep</code> interpreter loads libraries to <code>%spark</code> and <code>%spark.pyspark</code> but not to <code>%spark.sql</code> interpreter. So we recommend you to use the first option instead.</p>
+</blockquote>
+
+<p>When your code requires external library, instead of doing download/copy/restart Zeppelin, you can easily do following jobs using <code>%spark.dep</code> interpreter.</p>
+
+<ul>
+<li>Load libraries recursively from maven repository</li>
+<li>Load libraries from local filesystem</li>
+<li>Add additional maven repository</li>
+<li>Automatically add libraries to SparkCluster (You can turn off)</li>
+</ul>
+
+<p>Dep interpreter leverages Scala environment. So you can write any Scala code here.
+Note that <code>%spark.dep</code> interpreter should be used before <code>%spark</code>, <code>%spark.pyspark</code>, <code>%spark.sql</code>.</p>
+
+<p>Here's usages.</p>

+<h2>ZeppelinContext</h2>
+
+<p>Zeppelin automatically injects <code>ZeppelinContext</code> as variable <code>z</code> in your Scala/Python environment. <code>ZeppelinContext</code> provides some additional functions and utilities.
+See <a href="../usage/other_features/zeppelin_context.html">Zeppelin-Context</a> for more details.</p>
+
+<h2>Matplotlib Integration (pyspark)</h2>
+
+<p>Both the <code>python</code> and <code>pyspark</code> interpreters have built-in support for inline visualization using <code>matplotlib</code>,
+a popular plotting library for python. More details can be found in the <a href="../interpreter/python.html">python interpreter documentation</a>,
+since matplotlib support is identical. More advanced interactive plotting can be done with pyspark through
+utilizing Zeppelin's built-in <a href="../usage/display_system/angular_backend.html">Angular Display System</a>, as shown below:</p>
+
+<p><img class="img-responsive" src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/matplotlibAngularExample.gif" /></p>
+
+<h2>Interpreter setting option</h2>
+
+<p>You can choose one of <code>shared</code>, <code>scoped</code> and <code>isolated</code> options wheh you configure Spark interpreter.
+Spark interpreter creates separated Scala compiler per each notebook but share a single SparkContext in <code>scoped</code> mode (experimental).
+It creates separated SparkContext per each notebook in <code>isolated</code> mode.</p>
+
+<h2>IPython support</h2>
+
+<p>By default, zeppelin would use IPython in <code>pyspark</code> when IPython is available, Otherwise it would fall back to the original PySpark implementation.
+If you don't want to use IPython, then you can set <code>zeppelin.pyspark.useIPython</code> as <code>false</code> in interpreter setting. For the IPython features, you can refer doc
+<a href="python.html">Python Interpreter</a></p>
+
+<h2>Setting up Zeppelin with Kerberos</h2>
+
+<p>Logical setup with Zeppelin, Kerberos Key Distribution Center (KDC), and Spark on YARN:</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/kdc_zeppelin.png"></p>
+
+<h3>Configuration Setup</h3>
+
+<ol>
+<li><p>On the server that Zeppelin is installed, install Kerberos client modules and configuration, krb5.conf.
+This is to make the server communicate with KDC.</p></li>
+<li><p>Set <code>SPARK_HOME</code> in <code>[ZEPPELIN_HOME]/conf/zeppelin-env.sh</code> to use spark-submit
+(Additionally, you might have to set <code>export HADOOP_CONF_DIR=/etc/hadoop/conf</code>)</p></li>
+<li><p>Add the two properties below to Spark configuration (<code>[SPARK_HOME]/conf/spark-defaults.conf</code>):</p>
+<div class="highlight"><pre><code class="text language-text" data-lang="text">spark.yarn.principal
+spark.yarn.keytab
+</code></pre></div>
+<blockquote>
+<p><strong>NOTE:</strong> If you do not have permission to access for the above spark-defaults.conf file, optionally, you can add the above lines to the Spark Interpreter setting through the Interpreter tab in the Zeppelin UI.</p>
+</blockquote></li>
+<li><p>That's it. Play with Zeppelin!</p></li>

+<h1>Explore Apache Zeppelin UI</h1>
+
+<div id="toc"></div>
+
+<h2>Main home</h2>
+
+<p>The first time you connect to Zeppelin (<a href="http://localhost:8080/">default installations start on http://localhost:8080</a>), you'll land at the main page similar to the below screen capture.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/homepage.png" /></p>
+
+<p>On the left of the page are listed all existing notes. Those notes are stored by default in the <code>$ZEPPELIN_HOME/notebook</code> folder.</p>
+
+<p>You can filter them by name using the input text form. You can also create a new note, refresh the list of existing notes
+(in case you manually copy them into the <code>$ZEPPELIN_HOME/notebook</code> folder) and import a note.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/notes_management.png" width="230px" /></p>
+
+<p>When clicking on <code>Import Note</code> link, a new dialog open. From there you can import your note from local disk or from a remote location
+if you provide the URL.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/note_import_dialog.png" /></p>
+
+<p>By default, the name of the imported note is the same as the original note but you can override it by providing a new name.</p>
+
+<p><br /></p>
+
+<h2>Menus</h2>
+
+<h3>Notebook</h3>
+
+<p>The <code>Notebook</code> menu proposes almost the same features as the note management section in the home page. From the drop-down menu you can:</p>
+
+<ol>
+<li>Open a selected note</li>
+<li>Filter node by name</li>
+<li>Create a new note</li>
+</ol>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/notebook_menu.png" width="170px" /></p>
+
+<h3>Settings</h3>
+
+<p>This menu gives you access to settings and displays information about Zeppelin. User name is set to <code>anonymous</code> if you use default shiro configuration. If you want to set up authentification, see <a href="../setup/security/shiro_authentication.html">Shiro Authentication</a>.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/settings_menu.png" width="170px" /></p>

+
+<p>In this menu you can:</p>
+
+<ol>
+<li>Configure existing <strong>interpreter instance</strong></li>
+<li>Add/remove <strong>interpreter instances</strong></li>

+
+<h4>Credential</h4>
+
+<p>This menu allows you to save credentials for data sources which are passed to interpreters.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/credential_menu.png" /></p>
+

+
+<p><br /></p>
+
+<h2>Note Layout</h2>
+
+<p>Each Zeppelin note is composed of 1 .. N paragraphs. The note can be viewed as a paragraph container.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/note_paragraph_layout.png" /></p>
+
+<h3>Paragraph</h3>
+
+<p>Each paragraph consists of 2 sections: <code>code section</code> where you put your source code and <code>result section</code> where you can see the result of the code execution.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/paragraph_layout.png" /></p>
+
+<p>On the top-right corner of each paragraph there are some commands to:</p>
+
+<ul>
+<li>execute the paragraph code</li>
+<li>hide/show <code>code section</code></li>
+<li>hide/show <code>result section</code></li>
+<li>configure the paragraph</li>
+</ul>
+
+<p>To configure the paragraph, just click on the gear icon:</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/paragraph_configuration_dialog.png" width="180px" /></p>
+
+<p>From this dialog, you can (in descending order):</p>
+
+<ul>
+<li>find the <strong>paragraph id</strong> ( <strong>20150924-163507_134879501</strong> )</li>
+<li>control paragraph width. Since Zeppelin is using the grid system of <strong>Twitter Bootstrap</strong>, each paragraph width can be changed from 1 to 12</li>
+<li>move the paragraph 1 level up</li>
+<li>move the paragraph 1 level down</li>
+<li>create a new paragraph</li>
+<li>change paragraph title</li>
+<li>show/hide line number in the <code>code section</code></li>
+<li>disable the run button for this paragraph</li>
+<li>export the current paragraph as an <strong>iframe</strong> and open the <strong>iframe</strong> in a new window</li>
+<li>clear the <code>result section</code></li>
+<li>delete the current paragraph</li>
+</ul>
+
+<h3>Note toolbar</h3>
+
+<p>At the top of the note, you can find a toolbar which exposes command buttons as well as configuration, security and display options.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/note_toolbar.png" /></p>
+
+<p>On the far right is displayed the note name, just click on it to reveal the input form and update it.</p>
+
+<p>In the middle of the toolbar you can find the command buttons:</p>
+
+<ul>
+<li>execute all the paragraphs <strong>sequentially</strong>, in their display order</li>
+<li>hide/show <code>code section</code> of all paragraphs</li>
+<li>hide/show <code>result section</code> of all paragraphs</li>
+<li>clear the <code>result section</code> of all paragraphs</li>
+<li>clone the current note</li>
+<li>export the current note to a JSON file. _Please note that the <code>code section</code> and <code>result section</code> of all paragraphs will be exported. If you have heavy data in the <code>result section</code> of some paragraphs, it is recommended to clean them before exporting</li>
+<li>commit the current node content</li>
+<li>delete the note</li>
+<li>schedule the execution of <strong>all paragraph</strong> using a CRON syntax</li>
+</ul>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/ui-img/note_commands.png" width="300px"/></p>
+
+<p>On the right of the note tool bar you can find configuration icons:</p>
+
+<ul>
+<li>display all the keyboard shorcuts</li>
+<li>configure the interpreters binding to the current note</li>
+<li>configure the note permissions</li>
+<li>switch the node display mode between <code>default</code>, <code>simple</code> and <code>report</code></li>
