+<h1>Shell interpreter for Apache Zeppelin</h1>
+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p>Zeppelin Shell has two interpreters the default is the %sh interpreter.</p>
+
+<h3>Shell interpreter</h3>
+
+<p>Shell interpreter uses <a href="https://commons.apache.org/proper/commons-exec">Apache Commons Exec</a> to execute external processes.
+In Zeppelin notebook, you can use <code>%sh</code> in the beginning of a paragraph to invoke system shell and run commands.</p>
+
+<h3>Terminal interpreter</h3>
+
+<p>Terminal interpreter uses <a href="https://chromium.googlesource.com/apps/libapps/+/HEAD/hterm">hterm</a>, <a href="https://github.com/JetBrains/pty4j">Pty4J</a> analog terminal operation.</p>
+
+<blockquote>
+<p><strong>Note :</strong> Currently each command runs as the user Zeppelin server is running as.</p>
+</blockquote>
+
+<h2>Configuration</h2>
+
+<p>At the "Interpreters" menu in Zeppelin dropdown menu, you can set the property value for Shell interpreter.</p>
+
+<table class="table-configuration">
+ <tr>
+ <th>Name</th>
+ <th>Default</th>
+ <th>Description</th>
+ </tr>
+ <tr>
+ <td>shell.command.timeout.millisecs</td>
+ <td>60000</td>
+ <td>Shell command time out in millisecs</td>
+ </tr>
+ <tr>
+ <td>shell.working.directory.user.home</td>
+ <td>false</td>
+ <td>If this set to true, the shell's working directory will be set to user home</td>
+ </tr>
+ <tr>
+ <td>zeppelin.shell.auth.type</td>
+ <td></td>
+ <td>Types of authentications' methods supported are SIMPLE, and KERBEROS</td>
+ </tr>
+ <tr>
+ <td>zeppelin.shell.principal</td>
+ <td></td>
+ <td>The principal name to load from the keytab</td>
+ </tr>
+ <tr>
+ <td>zeppelin.shell.keytab.location</td>
+ <td></td>
+ <td>The path to the keytab file</td>
+ </tr>
+ <tr>
+ <td>zeppelin.shell.interpolation</td>
+ <td>false</td>
+ <td>Enable ZeppelinContext variable interpolation into paragraph text</td>
+ </tr>
+ <tr>
+ <td>zeppelin.terminal.ip.mapping</td>
+ <td></td>
+ <td>Internal and external IP mapping of zeppelin server</td>
+ </tr>
+</table>
+
+<h2>Example</h2>
+
+<h3>Shell interpreter</h3>
+
+<p>The following example demonstrates the basic usage of Shell in a Zeppelin notebook.</p>
+
+<p><img src="/docs/0.9.0/assets/themes/zeppelin/img/docs-img/shell-example.png" /></p>
+
+<p>If you need further information about <strong>Zeppelin Interpreter Setting</strong> for using Shell interpreter,
+please read <a href="../usage/interpreter/overview.html#what-is-interpreter-setting">What is interpreter setting?</a> section first.</p>
+
+<h3>Kerberos refresh interval</h3>
+
+<p>For changing the default behavior of when to renew Kerberos ticket following changes can be made in <code>conf/zeppelin-env.sh</code>.</p>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash"><span class="c"># Change Kerberos refresh interval (default value is 1d). Allowed postfix are ms, s, m, min, h, and d.</span>
+<span class="nb">export </span><span class="nv">KERBEROS_REFRESH_INTERVAL</span><span class="o">=</span>4h
+<span class="c"># Change kinit number retries (default value is 5), which means if the kinit command fails for 5 retries consecutively it will close the interpreter. </span>
+<span class="nb">export </span><span class="nv">KINIT_FAIL_THRESHOLD</span><span class="o">=</span>10
+</code></pre></div>
+<h3>Object Interpolation</h3>
+
+<p>The shell interpreter also supports interpolation of <code>ZeppelinContext</code> objects into the paragraph text.
+The following example shows one use of this facility:</p>
+
+<h4>In Scala cell:</h4>
+<div class="highlight"><pre><code class="scala language-scala" data-lang="scala"><span class="n">z</span><span class="o">.</span><span class="n">put</span><span class="o">(</span><span class="s">"dataFileName"</span><span class="o">,</span> <span class="s">"members-list-003.parquet"</span><span class="o">)</span>
+ <span class="c1">// ...</span>
+<span class="k">val</span> <span class="n">members</span> <span class="k">=</span> <span class="n">spark</span><span class="o">.</span><span class="n">read</span><span class="o">.</span><span class="n">parquet</span><span class="o">(</span><span class="n">z</span><span class="o">.</span><span class="n">get</span><span class="o">(</span><span class="s">"dataFileName"</span><span class="o">))</span>
+ <span class="c1">// ...</span>
+</code></pre></div>
+<h4>In later Shell cell:</h4>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash">%sh
+rm -rf <span class="o">{</span>dataFileName<span class="o">}</span>
+</code></pre></div>
+<p>Object interpolation is disabled by default, and can be enabled (for the Shell interpreter) by
+setting the value of the property <code>zeppelin.shell.interpolation</code> to <code>true</code> (see <em>Configuration</em> above).
+More details of this feature can be found in <a href="../usage/other_features/zeppelin_context.html">Zeppelin-Context</a></p>
+
+<h3>Terminal interpreter</h3>
+
+<p>The following example demonstrates the basic usage of terminal in a Zeppelin notebook.</p>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash">%sh.terminal
+input any char
+</code></pre></div>
+<p><img src="/docs/0.9.0/assets/themes/zeppelin/img/docs-img/shell-terminal.gif" /></p>
+
+<h3>zeppelin.terminal.ip.mapping</h3>
+
+<p>When running the terminal interpreter in the notebook, the front end of the notebook needs to obtain the IP address of the server where the terminal interpreter is located to communicate.</p>
+
+<p>In a public cloud environment, the cloud host has an internal IP and an external access IP, and the interpreter runs in the cloud host. This will cause the notebook front end to be unable to connect to the terminal interpreter properly, resulting in the terminal interpreter being unusable.</p>
+
+<p>Solution: Set the mapping between internal IP and external IP in the terminal interpreter, and connect the front end of the notebook through the external IP of the terminal interpreter.</p>
+
+<p>Example:
+{"internal-ip1":"external-ip1", "internal-ip2":"external-ip2"}</p>

+<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 six 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>Export SPARK_HOME</h3>
+
+<p>There are several options for setting <code>SPARK_HOME</code>.</p>
+
+<ul>
+<li>Set <code>SPARK_HOME</code> in <code>zeppelin-env.sh</code></li>
+<li>Set <code>SPARK_HOME</code> in Interpreter setting page</li>
+<li>Set <code>SPARK_HOME</code> via <a href="../usage/interpreter/overview.html#inline-generic-confinterpreter">inline generic configuration</a> </li>
+</ul>
+
+<h4>1. Set <code>SPARK_HOME</code> in <code>zeppelin-env.sh</code></h4>
+
+<p>If you work with only one version of spark, then you can set <code>SPARK_HOME</code> in <code>zeppelin-env.sh</code> because any setting in <code>zeppelin-env.sh</code> is globally applied.</p>
+
+<p>e.g. </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 in <code>zeppelin-env.sh</code></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
+</code></pre></div>
+<h4>2. Set <code>SPARK_HOME</code> in Interpreter setting page</h4>
+
+<p>If you want to use multiple versions of spark, then you need create multiple spark interpreters and set <code>SPARK_HOME</code> for each of them. e.g.
+Create a new spark interpreter <code>spark24</code> for spark 2.4 and set <code>SPARK_HOME</code> in interpreter setting page
+<center>
+<img src="/docs/0.9.0/assets/themes/zeppelin/img/docs-img/spark_SPARK_HOME24.png" width="80%">
+</center></p>
+
+<p>Create a new spark interpreter <code>spark16</code> for spark 1.6 and set <code>SPARK_HOME</code> in interpreter setting page
+<center>
+<img src="/docs/0.9.0/assets/themes/zeppelin/img/docs-img/spark_SPARK_HOME16.png" width="80%">
+</center></p>
+
+<h4>3. Set <code>SPARK_HOME</code> via <a href="../usage/interpreter/overview.html#inline-generic-confinterpreter">inline generic configuration</a></h4>
+
+<p>Besides setting <code>SPARK_HOME</code> in interpreter setting page, you can also use inline generic configuration to put the
+configuration with code together for more flexibility. e.g.
+<center>
+<img src="/docs/0.9.0/assets/themes/zeppelin/img/docs-img/spark_inline_configuration.png" width="80%">
+</center></p>
+
+<h3>Set master in Interpreter menu</h3>
+
+<p>After starting Zeppelin, go to <strong>Interpreter</strong> menu and edit <strong>spark.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 (Not supported in spark 3.x, refer below for how to configure yarn-client in Spark 3.x)</li>
+<li><strong>yarn-cluster</strong> in Yarn cluster mode (Not supported in spark 3.x, refer below for how to configure yarn-client in Spark 3.x)</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>
+
+<p>Yarn client mode and local mode will run driver in the same machine with zeppelin server, this would be dangerous for production. Because it may run out of memory when there's many spark interpreters running at the same time. So we suggest you only allow yarn-cluster mode via setting <code>zeppelin.spark.only_yarn_cluster</code> in <code>zeppelin-site.xml</code>.</p>
+</blockquote>
+
+<h4>Configure yarn mode for Spark 3.x</h4>
+
+<p>Specifying <code>yarn-client</code> & <code>yarn-cluster</code> in <code>spark.master</code> is not supported in Spark 3.x any more, instead you need to use <code>spark.master</code> and <code>spark.submit.deployMode</code> together.</p>
+
+<table class="table-configuration">
+ <tr>
+ <th>Mode</th>
+ <th>spark.master</th>
+ <th>spark.submit.deployMode</th>
+ </tr>
+ <tr>
+ <td>Yarn Client</td>
+ <td>yarn</td>
+ <td>client</td>
+ </tr>
+ <tr>
+ <td>Yarn Cluster</td>
+ <td>yarn</td>
+ <td>cluster</td>
+ </tr>
+</table>
+
+<h2>SparkContext, SQLContext, SparkSession, ZeppelinContext</h2>
+
+<p>SparkContext, SQLContext, SparkSession (for spark 2.x) and ZeppelinContext are automatically created and exposed as variable names <code>sc</code>, <code>sqlContext</code>, <code>spark</code> and <code>z</code>, respectively, in Scala, Kotlin, Python and R environments.</p>
+
+<blockquote>
+<p>Note that Scala/Python/R environment shares the same SparkContext, SQLContext, SparkSession and ZeppelinContext instance.</p>
+</blockquote>
+
+<h2>YARN Mode</h2>
+
+<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>.
+Usually you only have one hadoop cluster, so you can set <code>HADOOP_CONF_DIR</code> in <code>zeppelin-env.sh</code> which is applied to all spark interpreters. If you want to use spark against multiple hadoop cluster, then you need to define
+<code>HADOOP_CONF_DIR</code> in interpreter setting or via inline generic configuration.</p>
+
+<h2>Dependency Management</h2>
+
+<p>For spark interpreter, it is not recommended to use Zeppelin's <a href="../usage/interpreter/dependency_management.html">Dependency Management</a> for managing
+third party dependencies (<code>%spark.dep</code> is removed from Zeppelin 0.9 as well). Instead you should set the standard Spark properties.</p>
+
+<table class="table-configuration">
+ <tr>
+ <th>Spark Property</th>
+ <th>Spark Submit Argument</th>
+ <th>Description</th>
+ </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. Globs are allowed.</td>
+ </tr>
+ <tr>
+ <td>spark.jars</td>
+ <td>--jars</td>
+ <td>Comma-separated list of jars to include on the driver and executor classpaths. Globs are allowed.</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. The coordinates should be groupId:artifactId:version. If spark.jars.ivySettings is given artifacts will be resolved according to the configuration in the file, otherwise artifacts will be searched for in the local maven repo, then maven central and finally any additional remote repositories given by the command-line option --repositories.</td>
+ </tr>
+</table>
+
+<p>You can either set Spark properties in interpreter setting page or set Spark submit arguments in <code>zeppelin-env.sh</code> via environment variable <code>SPARK_SUBMIT_OPTIONS</code>.
+For examples:</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">"--files <my_file> --jars <my_jar> --packages <my_package>"</span>
+</code></pre></div>
+<p>But it is not recommended to set them in <code>SPARK_SUBMIT_OPTIONS</code>. Because it will be shared by all spark interpreters, which means you can not set different dependencies for different users.</p>
+
+<h2>PySpark</h2>
+
+<p>There're 2 ways to use PySpark in Zeppelin:</p>
+
+<ul>
+<li>Vanilla PySpark</li>
+<li>IPySpark</li>
+</ul>
+
+<h3>Vanilla PySpark (Not Recommended)</h3>
+
+<p>Vanilla PySpark interpreter is almost the same as vanilla Python interpreter except Zeppelin inject SparkContext, SQLContext, SparkSession via variables <code>sc</code>, <code>sqlContext</code>, <code>spark</code>.</p>
+
+<p>By default, Zeppelin would use IPython in <code>%spark.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>
+
+<h3>IPySpark (Recommended)</h3>
+
+<p>You can use <code>IPySpark</code> explicitly via <code>%spark.ipyspark</code>. IPySpark interpreter is almost the same as IPython interpreter except Zeppelin inject SparkContext, SQLContext, SparkSession via variables <code>sc</code>, <code>sqlContext</code>, <code>spark</code>.
+For the IPython features, you can refer doc <a href="python.html">Python Interpreter</a></p>
+
+<h2>SparkR</h2>
+
+<p>Zeppelin support SparkR via <code>%spark.r</code>. Here's configuration for SparkR Interpreter.</p>
+
+<table class="table-configuration">
+ <tr>
+ <th>Spark Property</th>
+ <th>Default</th>
+ <th>Description</th>
+ </tr>
+ <tr>
+ <td>zeppelin.R.cmd</td>
+ <td>R</td>
+ <td>R binary executable path.</td>
+ </tr>
+ <tr>
+ <td>zeppelin.R.knitr</td>
+ <td>true</td>
+ <td>Whether use knitr or not. (It is recommended to install knitr and use it in Zeppelin)</td>
+ </tr>
+ <tr>
+ <td>zeppelin.R.image.width</td>
+ <td>100%</td>
+ <td>R plotting image width.</td>
+ </tr>
+ <tr>
+ <td>zeppelin.R.render.options</td>
+ <td>out.format = 'html', comment = NA, echo = FALSE, results = 'asis', message = F, warning = F, fig.retina = 2</td>
+ <td>R plotting options.</td>
+ </tr>
+</table>
+
+<h2>SparkSql</h2>
+
+<p>Spark Sql Interpreter share the same SparkContext/SparkSession with other Spark interpreter. That means any table registered in scala, python or r code can be accessed by Spark Sql.
+For examples:</p>
+<div class="highlight"><pre><code class="scala language-scala" data-lang="scala"><span class="o">%</span><span class="n">spark</span>
+
+<span class="k">case</span> <span class="k">class</span> <span class="nc">People</span><span class="o">(</span><span class="n">name</span><span class="k">:</span> <span class="kt">String</span><span class="o">,</span> <span class="n">age</span><span class="k">:</span> <span class="kt">Int</span><span class="o">)</span>
+<span class="k">var</span> <span class="n">df</span> <span class="k">=</span> <span class="n">spark</span><span class="o">.</span><span class="n">createDataFrame</span><span class="o">(</span><span class="nc">List</span><span class="o">(</span><span class="nc">People</span><span class="o">(</span><span class="s">"jeff"</span><span class="o">,</span> <span class="mi">23</span><span class="o">),</span> <span class="nc">People</span><span class="o">(</span><span class="s">"andy"</span><span class="o">,</span> <span class="mi">20</span><span class="o">)))</span>
+<span class="n">df</span><span class="o">.</span><span class="n">createOrReplaceTempView</span><span class="o">(</span><span class="s">"people"</span><span class="o">)</span>
+</code></pre></div><div class="highlight"><pre><code class="sql language-sql" data-lang="sql"><span class="o">%</span><span class="n">spark</span><span class="p">.</span><span class="k">sql</span>
+
+<span class="k">select</span> <span class="o">*</span> <span class="k">from</span> <span class="n">people</span>
+</code></pre></div>
+<p>By default, each sql statement would run sequentially in <code>%spark.sql</code>. But you can run them concurrently by following setup.</p>
+
+<ol>
+<li>Set <code>zeppelin.spark.concurrentSQL</code> to true to enable the sql concurrent feature, underneath zeppelin will change to use fairscheduler for spark. And also set <code>zeppelin.spark.concurrentSQL.max</code> to control the max number of sql statements running concurrently.</li>
+<li>Configure pools by creating <code>fairscheduler.xml</code> under your <code>SPARK_CONF_DIR</code>, check the official spark doc <a href="http://spark.apache.org/docs/latest/job-scheduling.html#configuring-pool-properties">Configuring Pool Properties</a></li>
+<li>Set pool property via setting paragraph property. e.g.</li>
+</ol>
+<div class="highlight"><pre><code class="text language-text" data-lang="text">%spark(pool=pool1)
+
+sql statement
+</code></pre></div>
+<p>This pool feature is also available for all versions of scala Spark, PySpark. For SparkR, it is only available starting from 2.3.0.</p>
+
+<h2>Interpreter Setting Option</h2>
+
+<p>You can choose one of <code>shared</code>, <code>scoped</code> and <code>isolated</code> options when you configure Spark interpreter.
+e.g. </p>
+
+<ul>
+<li>In <code>scoped</code> per user mode, Zeppelin creates separated Scala compiler for each user but share a single SparkContext.</li>
+<li>In <code>isolated</code> per user mode, Zeppelin creates separated SparkContext for each user.</li>
+</ul>
+
+<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>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/0.9.0/assets/themes/zeppelin/img/docs-img/kdc_zeppelin.png"></p>
+
+<p>There're several ways to make spark work with kerberos enabled hadoop cluster in Zeppelin. </p>
+
+<ol>
+<li><p>Share one single hadoop cluster.
+In this case you just need to specify <code>zeppelin.server.kerberos.keytab</code> and <code>zeppelin.server.kerberos.principal</code> in zeppelin-site.xml, Spark interpreter will use these setting by default.</p></li>
+<li><p>Work with multiple hadoop clusters.
+In this case you can specify <code>spark.yarn.keytab</code> and <code>spark.yarn.principal</code> to override <code>zeppelin.server.kerberos.keytab</code> and <code>zeppelin.server.kerberos.principal</code>.</p></li>
+</ol>
+
+<h2>User Impersonation</h2>
+
+<p>In yarn mode, the user who launch the zeppelin server will be used to launch the spark yarn application. This is not a good practise.
+Most of time, you will enable shiro in Zeppelin and would like to use the login user to submit the spark yarn app. For this purpose,
+you need to enable user impersonation for more security control. In order the enable user impersonation, you need to do the following steps</p>
+
+<p><strong>Step 1</strong> Enable user impersonation setting hadoop's <code>core-site.xml</code>. E.g. if you are using user <code>zeppelin</code> to launch Zeppelin, then add the following to <code>core-site.xml</code>, then restart both hdfs and yarn. </p>
+<div class="highlight"><pre><code class="text language-text" data-lang="text"><property>
+ <name>hadoop.proxyuser.zeppelin.groups</name>
+ <value>*</value>
+</property>
+<property>
+ <name>hadoop.proxyuser.zeppelin.hosts</name>
+ <value>*</value>
+</property>
+</code></pre></div>
+<p><strong>Step 2</strong> Enable interpreter user impersonation in Spark interpreter's interpreter setting. (Enable shiro first of course)
+<img src="/docs/0.9.0/assets/themes/zeppelin/img/docs-img/spark_user_impersonation.png"></p>
+
+<p><strong>Step 3(Optional)</strong> If you are using kerberos cluster, then you need to set <code>zeppelin.server.kerberos.keytab</code> and <code>zeppelin.server.kerberos.principal</code> to the user(aka. user in Step 1) you want to
+impersonate in <code>zeppelin-site.xml</code>.</p>
+
+<h2>Deprecate Spark 2.2 and earlier versions</h2>
+
+<p>Starting from 0.9, Zeppelin deprecate Spark 2.2 and earlier versions. So you will see a warning message when you use Spark 2.2 and earlier.
+You can get rid of this message by setting <code>zeppelin.spark.deprecatedMsg.show</code> to <code>false</code>.</p>
+
+<p><img src="/docs/0.9.0/assets/themes/zeppelin/img/docs-img/spark_deprecate.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>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>
