+
+<h2>Overview</h2>
+
+<p><a href="http://livy.io/">Livy</a> is an open source REST interface for interacting with Spark from anywhere. It supports executing snippets of code or programs in a Spark context that runs locally or in YARN.</p>
+
+<ul>
+<li>Interactive Scala, Python and R shells</li>
+<li>Batch submissions in Scala, Java, Python</li>
+<li>Multi users can share the same server (impersonation support)</li>
+<li>Can be used for submitting jobs from anywhere with REST</li>
+<li>Does not require any code change to your programs</li>
+</ul>
+
+<h3>Requirements</h3>
+
+<p>Additional requirements for the Livy interpreter are:</p>
+
+<ul>
+<li>Spark 1.3 or above.</li>
+<li>Livy server.</li>
+</ul>
+
+<h2>Configuration</h2>
+
+<p>We added some common configurations for spark, and you can set any configuration you want.
+This link contains all spark configurations: http://spark.apache.org/docs/latest/configuration.html#available-properties.
+And instead of starting property with <code>spark.</code> it should be replaced with <code>livy.spark.</code>.
+Example: <code>spark.master</code> to <code>livy.spark.master</code></p>
+
+<table class="table-configuration">
+ <tr>
+ <th>Property</th>
+ <th>Default</th>
+ <th>Description</th>
+ </tr>
+ <tr>
+ <td>livy.spark.master</td>
+ <td>local[*]</td>
+ <td>Spark master uri. ex) spark://masterhost:7077</td>
+ </tr>
+ <tr>
+ <td>zeppelin.livy.url</td>
+ <td>http://localhost:8998</td>
+ <td>URL where livy server is running</td>
+ </tr>
+ <tr>
+ <td>zeppelin.livy.spark.maxResult</td>
+ <td>1000</td>
+ <td>Max number of SparkSQL result to display.</td>
+ </tr>
+ <tr>
+ <td>livy.spark.driver.cores</td>
+ <td></td>
+ <td>Driver cores. ex) 1, 2.</td>
+ </tr>
+ <tr>
+ <td>livy.spark.driver.memory</td>
+ <td></td>
+ <td>Driver memory. ex) 512m, 32g.</td>
+ </tr>
+ <tr>
+ <td>livy.spark.executor.instances</td>
+ <td></td>
+ <td>Executor instances. ex) 1, 4.</td>
+ </tr>
+ <tr>
+ <td>livy.spark.executor.cores</td>
+ <td></td>
+ <td>Num cores per executor. ex) 1, 4.</td>
+ </tr>
+ <tr>
+ <td>livy.spark.executor.memory</td>
+ <td></td>
+ <td>Executor memory per worker instance. ex) 512m, 32g.</td>
+ </tr>
+ <tr>
+ <td>livy.spark.dynamicAllocation.enabled</td>
+ <td></td>
+ <td>Use dynamic resource allocation. ex) True, False.</td>
+ </tr>
+ <tr>
+ <td>livy.spark.dynamicAllocation.cachedExecutorIdleTimeout</td>
+ <td></td>
+ <td>Remove an executor which has cached data blocks.</td>
+ </tr>
+ <tr>
+ <td>livy.spark.dynamicAllocation.minExecutors</td>
+ <td></td>
+ <td>Lower bound for the number of executors.</td>
+ </tr>
+ <tr>
+ <td>livy.spark.dynamicAllocation.initialExecutors</td>
+ <td></td>
+ <td>Initial number of executors to run.</td>
+ </tr>
+ <tr>
+ <td>livy.spark.dynamicAllocation.maxExecutors</td>
+ <td></td>
+ <td>Upper bound for the number of executors.</td>
+ </tr>
+</table>
+
+<h2>How to use</h2>
+
+<p>Basically, you can use</p>
+
+<p><strong>spark</strong></p>
+<div class="highlight"><pre><code class="text language-text" data-lang="text">%livy.spark
+sc.version
+</code></pre></div>
+<p><strong>pyspark</strong></p>
+<div class="highlight"><pre><code class="text language-text" data-lang="text">%livy.pyspark
+print "1"
+</code></pre></div>
+<p><strong>sparkR</strong></p>
+<div class="highlight"><pre><code class="text language-text" data-lang="text">%livy.sparkr
+hello <- function( name ) {
+ sprintf( "Hello, %s", name );
+}
+
+hello("livy")
+</code></pre></div>
+<h2>Impersonation</h2>
+
+<p>When Zeppelin server is running with authentication enabled, then this interpreter utilizes Livy’s user impersonation feature i.e. sends extra parameter for creating and running a session ("proxyUser": "${loggedInUser}"). This is particularly useful when multi users are sharing a Notebook server.</p>
+
+<h2>Apply Zeppelin Dynamic Forms</h2>
+
+<p>You can leverage <a href="/docs/0.6.2/manual/dynamicform.html">Zeppelin Dynamic Form</a>. You can use both the <code>text input</code> and <code>select form</code> parameterization features.</p>
+<div class="highlight"><pre><code class="text language-text" data-lang="text">%livy.pyspark
+print "${group_by=product_id,product_id|product_name|customer_id|store_id}"
+</code></pre></div>
+<h2>FAQ</h2>
+
+<p>Livy debugging: If you see any of these in error console</p>
+
+<blockquote>
+<p>Connect to livyhost:8998 [livyhost/127.0.0.1, livyhost/0:0:0:0:0:0:0:1] failed: Connection refused</p>
+</blockquote>
+
+<p>Looks like the livy server is not up yet or the config is wrong</p>
+
+<blockquote>
+<p>Exception: Session not found, Livy server would have restarted, or lost session.</p>
+</blockquote>
+
+<p>The session would have timed out, you may need to restart the interpreter.</p>
+
+<blockquote>
+<p>Blacklisted configuration values in session config: spark.master</p>
+</blockquote>
+
+<p>Edit <code>conf/spark-blacklist.conf</code> file in livy server and comment out <code>#spark.master</code> line.</p>
+
+<p>If you choose to work on livy in <code>apps/spark/java</code> directory in <a href="https://github.com/cloudera/hue">https://github.com/cloudera/hue</a>,
+copy <code>spark-user-configurable-options.template</code> to <code>spark-user-configurable-options.conf</code> file in livy server and comment out <code>#spark.master</code>. </p>

+
+<h2>Overview</h2>
+
+<p><a href="http://daringfireball.net/projects/markdown/">Markdown</a> is a plain text formatting syntax designed so that it can be converted to HTML.
+Zeppelin uses markdown4j. For more examples and extension support, please checkout <a href="https://code.google.com/p/markdown4j/">here</a>.<br>
+In Zeppelin notebook, you can use <code>%md</code> in the beginning of a paragraph to invoke the Markdown interpreter and generate static html from Markdown plain text.</p>
+
+<p>In Zeppelin, Markdown interpreter is enabled by default.</p>
+
+<p><img src="/docs/0.6.2/assets/themes/zeppelin/img/docs-img/markdown-interpreter-setting.png" width="60%" /></p>
+
+<h2>Example</h2>
+

+<h2>Create Interpreter</h2>
+
+<p>By default Zeppelin creates one <code>PSQL</code> instance. You can remove it or create new instances.</p>
+
+<p>Multiple PSQL instances can be created, each configured to the same or different backend databases. But over time a <code>Notebook</code> can have only one PSQL interpreter instance <code>bound</code>. That means you <em>cannot</em> connect to different databases in the same <code>Notebook</code>. This is a known Zeppelin limitation.</p>
+
+<p>To create new PSQL instance open the <code>Interpreter</code> section and click the <code>+Create</code> button. Pick a <code>Name</code> of your choice and from the <code>Interpreter</code> drop-down select <code>psql</code>. Then follow the configuration instructions and <code>Save</code> the new instance.</p>
+
+<blockquote>
+<p>Note: The <code>Name</code> of the instance is used only to distinct the instances while binding them to the <code>Notebook</code>. The <code>Name</code> is irrelevant inside the <code>Notebook</code>. In the <code>Notebook</code> you must use <code>%psql.sql</code> tag.</p>
+</blockquote>
+
+<h2>Bind to Notebook</h2>
+
+<p>In the <code>Notebook</code> click on the <code>settings</code> icon in the top right corner. The select/deselect the interpreters to be bound with the <code>Notebook</code>.</p>
+
+<h2>Configuration</h2>
+
+<p>You can modify the configuration of the PSQL from the <code>Interpreter</code> section. The PSQL interpreter expenses the following properties:</p>
+
+<table class="table-configuration">
+ <tr>
+ <th>Property Name</th>
+ <th>Description</th>
+ <th>Default Value</th>
+ </tr>
+ <tr>
+ <td>postgresql.url</td>
+ <td>JDBC URL to connect to </td>
+ <td>jdbc:postgresql://localhost:5432</td>
+ </tr>
+ <tr>
+ <td>postgresql.user</td>
+ <td>JDBC user name</td>
+ <td>gpadmin</td>
+ </tr>
+ <tr>
+ <td>postgresql.password</td>
+ <td>JDBC password</td>
+ <td></td>
+ </tr>
+ <tr>
+ <td>postgresql.driver.name</td>
+ <td>JDBC driver name. In this version the driver name is fixed and should not be changed</td>
+ <td>org.postgresql.Driver</td>
+ </tr>
+ <tr>
+ <td>postgresql.max.result</td>
+ <td>Max number of SQL result to display to prevent the browser overload</td>
+ <td>1000</td>
+ </tr>
+</table>
+
+<h2>How to use</h2>
+<div class="highlight"><pre><code class="text language-text" data-lang="text">Tip: Use (CTRL + .) for SQL auto-completion.
+</code></pre></div>
+<h3>DDL and SQL commands</h3>
+
+<p>Start the paragraphs with the full <code>%psql.sql</code> prefix tag! The short notation: <code>%psql</code> would still be able run the queries but the syntax highlighting and the auto-completions will be disabled.</p>
+
+<p>You can use the standard CREATE / DROP / INSERT commands to create or modify the data model:</p>
+<div class="highlight"><pre><code class="sql language-sql" data-lang="sql"><span class="o">%</span><span class="n">psql</span><span class="p">.</span><span class="k">sql</span>
+<span class="k">drop</span> <span class="k">table</span> <span class="n">if</span> <span class="k">exists</span> <span class="n">mytable</span><span class="p">;</span>
+<span class="k">create</span> <span class="k">table</span> <span class="n">mytable</span> <span class="p">(</span><span class="n">i</span> <span class="nb">int</span><span class="p">);</span>
+<span class="k">insert</span> <span class="k">into</span> <span class="n">mytable</span> <span class="k">select</span> <span class="n">generate_series</span><span class="p">(</span><span class="mi">1</span><span class="p">,</span> <span class="mi">100</span><span class="p">);</span>
+</code></pre></div>
+<p>Then in a separate paragraph run the query.</p>
+<div class="highlight"><pre><code class="sql language-sql" data-lang="sql"><span class="o">%</span><span class="n">psql</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">mytable</span><span class="p">;</span>
+</code></pre></div>
+<blockquote>
+<p>Note: You can have multiple queries in the same paragraph but only the result from the first is displayed. [<a href="https://issues.apache.org/jira/browse/ZEPPELIN-178">1</a>], [<a href="https://issues.apache.org/jira/browse/ZEPPELIN-212">2</a>].</p>
+</blockquote>
+
+<p>For example, this will execute both queries but only the count result will be displayed. If you revert the order of the queries the mytable content will be shown instead.</p>
+<div class="highlight"><pre><code class="sql language-sql" data-lang="sql"><span class="o">%</span><span class="n">psql</span><span class="p">.</span><span class="k">sql</span>
+<span class="k">select</span> <span class="k">count</span><span class="p">(</span><span class="o">*</span><span class="p">)</span> <span class="k">from</span> <span class="n">mytable</span><span class="p">;</span>
+<span class="k">select</span> <span class="o">*</span> <span class="k">from</span> <span class="n">mytable</span><span class="p">;</span>
+</code></pre></div>
+<h3>PSQL command line tools</h3>
+
+<p>Use the Shell Interpreter (<code>%sh</code>) to access the command line <a href="http://www.postgresql.org/docs/9.4/static/app-psql.html">PSQL</a> interactively:</p>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash">%sh
+psql -h phd3.localdomain -U gpadmin -p 5432 <span class="s"><<EOF</span>
+<span class="s"> \dn </span>
+<span class="s"> \q</span>
+<span class="s">EOF</span>
+</code></pre></div>
+<p>This will produce output like this:</p>
+<div class="highlight"><pre><code class="text language-text" data-lang="text"> Name | Owner
+--------------------+---------
+ hawq_toolkit | gpadmin
+ information_schema | gpadmin
+ madlib | gpadmin
+ pg_catalog | gpadmin
+ pg_toast | gpadmin
+ public | gpadmin
+ retail_demo | gpadmin
+</code></pre></div>
+<h3>Apply Zeppelin Dynamic Forms</h3>
+
+<p>You can leverage <a href="../manual/dynamicform.html">Zeppelin Dynamic Form</a> inside your queries. You can use both the <code>text input</code> and <code>select form</code> parametrization features</p>
+<div class="highlight"><pre><code class="sql language-sql" data-lang="sql"><span class="o">%</span><span class="n">psql</span><span class="p">.</span><span class="k">sql</span>

+<h2>Auto-completion</h2>
+
+<p>The PSQL Interpreter provides a basic auto-completion functionality. On <code>(Ctrl+.)</code> it list the most relevant suggestions in a pop-up window. In addition to the SQL keyword the interpreter provides suggestions for the Schema, Table, Column names as well.</p>

+
+<h2>Enabling Python Interpreter</h2>
+
+<p>In a notebook, to enable the <strong>Python</strong> interpreter, click on the <strong>Gear</strong> icon and select <strong>Python</strong></p>
+
+<h2>Using the Python Interpreter</h2>
+
+<p>In a paragraph, use <strong><em>%python</em></strong> to select the <strong>Python</strong> interpreter and then input all commands.</p>
+
+<p>The interpreter can only work if you already have python installed (the interpreter doesn't bring it own python binaries).</p>
+
+<p>To access the help, type <strong>help()</strong></p>
+
+<h2>Python modules</h2>
+
+<p>The interpreter can use all modules already installed (with pip, easy_install...)</p>
+
+<h2>Use Zeppelin Dynamic Forms</h2>
+
+<p>You can leverage <a href="/docs/0.6.2/manual/dynamicform.html">Zeppelin Dynamic Form</a> inside your Python code.</p>
+
+<p><strong>Zeppelin Dynamic Form can only be used if py4j Python library is installed in your system. If not, you can install it with <code>pip install py4j</code>.</strong></p>
+
+<p>Example : </p>
+<div class="highlight"><pre><code class="python language-python" data-lang="python"><span class="o">%</span><span class="n">python</span>
+<span class="c">### Input form</span>
+<span class="k">print</span> <span class="p">(</span><span class="n">z</span><span class="o">.</span><span class="n">input</span><span class="p">(</span><span class="s">"f1"</span><span class="p">,</span><span class="s">"defaultValue"</span><span class="p">))</span>

+</code></pre></div>
+<h2>Zeppelin features not fully supported by the Python Interpreter</h2>
+
+<ul>
+<li>Interrupt a paragraph execution (<code>cancel()</code> method) is currently only supported in Linux and MacOs. If interpreter runs in another operating system (for instance MS Windows) , interrupt a paragraph will close the whole interpreter. A JIRA ticket (<a href="https://issues.apache.org/jira/browse/ZEPPELIN-893">ZEPPELIN-893</a>) is opened to implement this feature in a next release of the interpreter.</li>
+<li>Progression bar in webUI (<code>getProgress()</code> method) is currently not implemented.</li>
+<li>Code-completion is currently not implemented.</li>
+</ul>
+
+<h2>Matplotlib integration</h2>
+
+<p>The python interpreter can display matplotlib graph with the function <code>z.show()</code>.
+ You need to have matplotlib module installed and a XServer running to use this functionality !</p>
+<div class="highlight"><pre><code class="python language-python" data-lang="python"><span class="o">%</span><span class="n">python</span>

+</code></pre></div>
+<p><img class="img-responsive" src="../assets/themes/zeppelin/img/docs-img/pythonMatplotlib.png" /></p>
+
+<h2>Pandas integration</h2>
+
+<p><a href="/docs/0.6.2/displaysystem/basicdisplaysystem.html#table">Zeppelin Display System</a> provides simple API to visualize data in Pandas DataFrames, same as in Matplotlib.</p>
+
+<p>Example:</p>
+<div class="highlight"><pre><code class="python language-python" data-lang="python"><span class="kn">import</span> <span class="nn">pandas</span> <span class="kn">as</span> <span class="nn">pd</span>
