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="/assets/themes/zeppelin/img/docs-img/lens-logo.png" alt="Apache Lens"></p> + +<h3>Installing and Running Lens</h3> + +<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><p>Now, you can start lens server (or stop).</p> +<div class="highlight"><pre><code class="text language-text" data-lang="text">./bin/lens-ctl start (or stop) +</code></pre></div></li> +</ol> + +<h3>Configuring Lens Interpreter</h3> + +<p>At the "Interpreters" menu, you can to edit Lens interpreter or create new one.

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>can not</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>Interprter</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> + +<h3>Bind to Notebook</h3> + +<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> + +<h3>Configuration</h3> + +<p>You can modify the configuration of the PSQL from the <code>Interpreter</code> section.
