+<h1>Lens Interpreter for Apache Zeppelin</h1>
+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p><a href="https://lens.apache.org/">Apache Lens</a> provides an Unified Analytics interface. Lens aims to cut the Data Analytics silos by providing a single view of data across multiple tiered data stores and optimal execution environment for the analytical query. It seamlessly integrates Hadoop with traditional data warehouses to appear like one.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/lens-logo.png" alt="Apache Lens"></p>
+
+<h2>Installing and Running Lens</h2>
+
+<p>In order to use Lens interpreters, you may install Apache Lens in some simple steps:</p>
+
+<ol>
+<li>Download Lens for latest version from <a href="http://www.apache.org/dyn/closer.lua/lens/2.3-beta">the ASF</a>. Or the older release can be found <a href="http://archive.apache.org/dist/lens/">in the Archives</a>.</li>
+<li>Before running Lens, you have to set HIVE<em>HOME and HADOOP</em>HOME. If you want to get more information about this, please refer to <a href="http://lens.apache.org/lenshome/install-and-run.html#Installation">here</a>. Lens also provides Pseudo Distributed mode. <a href="http://lens.apache.org/lenshome/pseudo-distributed-setup.html">Lens pseudo-distributed setup</a> is done by using <a href="https://www.docker.com/">docker</a>. Hive server and hadoop daemons are run as separate processes in lens pseudo-distributed setup.</li>
+<li>Now, you can start lens server (or stop).</li>
+</ol>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash">./bin/lens-ctl start <span class="c"># (or stop)</span>
+</code></pre></div>
+<h2>Configuring Lens Interpreter</h2>
+
+<p>At the &quot;Interpreters&quot; menu, you can edit Lens interpreter or create new one. Zeppelin provides these properties for Lens.</p>
+
+<table class="table-configuration">
+  <tr>
+    <th>Property Name</th>
+    <th>value</th>
+    <th>Description</th>
+  </tr>
+  <tr>
+    <td>lens.client.dbname</td>
+    <td>default</td>
+    <td>The database schema name</td>
+  </tr>
+  <tr>
+    <td>lens.query.enable.persistent.resultset</td>
+    <td>false</td>
+    <td>Whether to enable persistent resultset for queries. When enabled, server will fetch results from driver, custom format them if any and store in a configured location. The file name of query output is queryhandle-id, with configured extensions</td>
+  </tr>
+  <tr>
+    <td>lens.server.base.url</td>
+    <td>http://hostname:port/lensapi</td>
+    <td>The base url for the lens server. you have to edit "hostname" and "port" that you may use(ex. http://0.0.0.0:9999/lensapi)</td>
+   </tr>
+   <tr>
+    <td>lens.session.cluster.user </td>
+    <td>default</td>
+    <td>Hadoop cluster username</td>
+  </tr>
+  <tr>
+    <td>zeppelin.lens.maxResult</td>
+    <td>1000</td>
+    <td>Max number of rows to display</td>
+  </tr>
+  <tr>
+    <td>zeppelin.lens.maxThreads</td>
+    <td>10</td>
+    <td>If concurrency is true then how many threads?</td>
+  </tr>
+  <tr>
+    <td>zeppelin.lens.run.concurrent</td>
+    <td>true</td>
+    <td>Run concurrent Lens Sessions</td>
+  </tr>
+  <tr>
+    <td>xxx</td>
+    <td>yyy</td>
+    <td>anything else from [Configuring lens server](https://lens.apache.org/admin/config-server.html)</td>

+
+<h3>Interpreter Binding for Zeppelin Notebook</h3>
+
+<p>After configuring Lens interpreter, create your own notebook, then you can bind interpreters like below image.</p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/lens-interpreter-binding.png" alt="Zeppelin Notebook Interpreter Binding"></p>
+
+<p>For more interpreter binding information see <a href="../usage/interpreter/overview.html#interpreter-binding-mode">here</a>.</p>
+
+<h3>How to use</h3>
+
+<p>You can analyze your data by using <a href="http://lens.apache.org/user/olap-cube.html">OLAP Cube</a> <a href="http://lens.apache.org/user/cli.html">QL</a> which is a high level SQL like language to query and describe data sets organized in data cubes.
+You may experience OLAP Cube like this <a href="https://cwiki.apache.org/confluence/display/LENS/2015/07/13/20+Minute+video+demo+of+Apache+Lens+through+examples">Video tutorial</a>.
+As you can see in this video, they are using Lens Client Shell(<code>./bin/lens-cli.sh</code>). All of these functions also can be used on Zeppelin by using Lens interpreter.</p>
+
+<p><li> Create and Use (Switch) Databases.</p>

+<p><li> Create Dimtables and Fact.</p>
+<div class="highlight"><pre><code class="text language-text" data-lang="text">create dimtable your/path/to/lens/client/examples/resources/customer_table.xml
+</code></pre></div><div class="highlight"><pre><code class="text language-text" data-lang="text">create fact your/path/to/lens/client/examples/resources/sales-raw-fact.xml
+</code></pre></div>
+<p><li> Add partitions to Dimtable and Fact.</p>
+<div class="highlight"><pre><code class="text language-text" data-lang="text">dimtable add single-partition --dimtable_name customer_table --storage_name local 
+--path your/path/to/lens/client/examples/resources/customer-local-part.xml

+--path your/path/to/lens/client/examples/resources/sales-raw-local-parts.xml
+</code></pre></div>
+<p><li> Now, you can run queries on cubes.</p>
+<div class="highlight"><pre><code class="text language-text" data-lang="text">query execute cube select customer_city_name, product_details.description, 
+product_details.category, product_details.color, store_sales from sales 
+where time_range_in(delivery_time, &#39;2015-04-11-00&#39;, &#39;2015-04-13-00&#39;)
+</code></pre></div>
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/lens-result.png" alt="Lens Query Result"></p>
+
+<p>These are just examples that provided in advance by Lens. If you want to explore whole tutorials of Lens, see the <a href="https://cwiki.apache.org/confluence/display/LENS/2015/07/13/20+Minute+video+demo+of+Apache+Lens+through+examples">tutorial video</a>.</p>
+
+<h2>Lens UI Service</h2>
+
+<p>Lens also provides web UI service. Once the server starts up, you can open the service on http://serverhost:19999/index.html and browse. You may also check the structure that you made and use query easily here.</p>

+<h1>Livy Interpreter for Apache Zeppelin</h1>
+
+<div id="toc"></div>
+
+<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.
+You can find all Spark configurations in <a href="http://spark.apache.org/docs/latest/configuration.html#available-properties">here</a>.
+And instead of starting property with <code>spark.</code> it should be replaced with <code>livy.spark.</code>.
+Example: <code>spark.driver.memory</code> to <code>livy.spark.driver.memory</code></p>
+

+<p><strong>We remove livy.spark.master in zeppelin-0.7. Because we sugguest user to use livy 0.3 in zeppelin-0.7. And livy 0.3 don&#39;t allow to specify livy.spark.master, it enfornce yarn-cluster mode.</strong></p>
+
+<h2>Adding External libraries</h2>
+
+<p>You can load dynamic library to livy interpreter by set <code>livy.spark.jars.packages</code> property to comma-separated list of maven coordinates of jars to include on the driver and executor classpaths. The format for the coordinates should be groupId:artifactId:version.</p>
+
+<p>Example</p>
+
+<table class="table-configuration">
+  <tr>
+    <th>Property</th>
+    <th>Example</th>
+    <th>Description</th>
+  </tr>
+  <tr>
+      <td>livy.spark.jars.packages</td>
+      <td>io.spray:spray-json_2.10:1.3.1</td>
+      <td>Adding extra libraries to livy interpreter</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="scala language-scala" data-lang="scala"><span class="o">%</span><span class="n">livy</span><span class="o">.</span><span class="n">spark</span>
+<span class="n">sc</span><span class="o">.</span><span class="n">version</span>
+</code></pre></div>
+<p><strong>pyspark</strong></p>
+<div class="highlight"><pre><code class="python language-python" data-lang="python"><span class="o">%</span><span class="n">livy</span><span class="o">.</span><span class="n">pyspark</span>
+<span class="k">print</span> <span class="s">&quot;1&quot;</span>
+</code></pre></div>
+<p><strong>sparkR</strong></p>
+<div class="highlight"><pre><code class="r language-r" data-lang="r"><span class="o">%livy.sparkr</span>
+<span class="o">hello &lt;- function( name ) {</span>
+<span class="o">    sprintf( &quot;Hello, %</span>s<span class="s">&quot;, name );</span>
+<span class="s">}</span>
+
+<span class="s">hello(&quot;</span>livy<span class="s">&quot;</span><span class="err">)</span>
+</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 (&quot;proxyUser&quot;: &quot;${loggedInUser}&quot;).
+This is particularly useful when multi users are sharing a Notebook server.</p>
+
+<h2>Apply Zeppelin Dynamic Forms</h2>
+
+<p>You can leverage <a href="../usage/dynamic_form/intro.html">Zeppelin Dynamic Form</a>. Form templates is only avalible for livy sql interpreter.</p>
+<div class="highlight"><pre><code class="sql language-sql" data-lang="sql"><span class="o">%</span><span class="n">livy</span><span class="p">.</span><span class="k">sql</span>
+<span class="k">select</span> <span class="o">*</span> <span class="k">from</span> <span class="n">products</span> <span class="k">where</span> <span class="err">${</span><span class="n">product_id</span><span class="o">=</span><span class="mi">1</span><span class="err">}</span>
+</code></pre></div>
+<p>And creating dynamic formst programmatically is not feasible in livy interpreter, because ZeppelinContext is not available in livy interpreter.</p>
+
+<h2>Shared SparkContext</h2>
+
+<p>Starting from livy 0.5 which is supported by Zeppelin 0.8.0, SparkContext is shared between scala, python, r and sql.
+That means you can query the table via <code>%livy.sql</code> when this table is registered in <code>%livy.spark</code>, <code>%livy.pyspark</code>, <code>$livy.sparkr</code>.</p>
+
+<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>
