+
+<h2>Overview</h2>
+
+<p><a href="https://kylin.apache.org/">Apache Kylin</a> is an open source
Distributed Analytics Engine designed to provide SQL interface and
multi-dimensional analysis (OLAP) on Hadoop supporting extremely large
datasets, original contributed from eBay Inc. The interpreter assumes that
Apache Kylin has been installed and you can connect to Apache Kylin from the
machine Apache Zeppelin is installed.<br>
+To get start with Apache Kylin, please see <a
href="https://kylin.apache.org/docs15/index.html">Apache Kylin
Quickstart</a>.</p>
+
+<h2>Configuration</h2>

+<h2>Using the Apache Kylin Interpreter</h2>
+
+<p>In a paragraph, use <code>%kylin(project_name)</code> to select the
<strong>kylin</strong> interpreter, <strong>project name</strong> and then
input <strong>sql</strong>. If no project name defined, will use the default
project name from the above configuration.</p>

+<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/0.9.0/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 "Interpreters" 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>

+
+<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/0.9.0/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>

+<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>

user to use livy 0.3 in zeppelin-0.7. And livy 0.3 don't allow to specify

+
+<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">"1"</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 <- function( name ) {</span>
+<span class="o"> sprintf( "Hello, %</span>s<span class="s">",
name );</span>
+<span class="s">}</span>
+
+<span class="s">hello("</span>livy<span class="s">"</span><span
class="err">)</span>
+</code></pre></div>
+<h2>Impersonation</h2>
+
+<p>When Zeppelin server is running with authentication enabled,
+then this interpreter utilizes Livyâs user impersonation feature
+i.e. sends extra parameter for creating and running a session
("proxyUser": "${loggedInUser}").
+This is particularly useful when multi users are sharing a Notebook server.</p>
+
+<h2>Apply Zeppelin Dynamic Forms</h2>
+
+<p>You can leverage <a href="../usage/dynamic_form/intro.html">Zeppelin
Dynamic Form</a>. Form templates is only avalible for livy sql interpreter.</p>
+<div class="highlight"><pre><code class="sql language-sql"
data-lang="sql"><span class="o">%</span><span class="n">livy</span><span
class="p">.</span><span class="k">sql</span>
+<span class="k">select</span> <span class="o">*</span> <span
class="k">from</span> <span class="n">products</span> <span
class="k">where</span> <span class="err">${</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>
