+<h1>R Interpreter for Apache Zeppelin</h1>
+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p><a href="https://www.r-project.org">R</a> is a free software environment for statistical computing and graphics.</p>
+
+<p>To run R code and visualize plots in Apache Zeppelin, you will need R on your master node (or your dev laptop).</p>
+
+<ul>
+<li>For Centos: <code>yum install R R-devel libcurl-devel openssl-devel</code></li>
+<li>For Ubuntu: <code>apt-get install r-base</code></li>
+</ul>
+
+<p>Validate your installation with a simple R command:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text"><span></span>R -e &quot;print(1+1)&quot;
+</code></pre></div>
+<p>To enjoy plots, install additional libraries with:</p>
+
+<ul>
+<li>devtools with </li>
+</ul>
+<div class="highlight"><pre><code class="language-bash" data-lang="bash"><span></span>  R -e <span class="s2">&quot;install.packages(&#39;devtools&#39;, repos = &#39;http://cran.us.r-project.org&#39;)&quot;</span>
+</code></pre></div>
+<ul>
+<li>knitr with </li>
+</ul>
+<div class="highlight"><pre><code class="language-bash" data-lang="bash"><span></span>  R -e <span class="s2">&quot;install.packages(&#39;knitr&#39;, repos = &#39;http://cran.us.r-project.org&#39;)&quot;</span>
+</code></pre></div>
+<ul>
+<li>ggplot2 with</li>
+</ul>
+<div class="highlight"><pre><code class="language-bash" data-lang="bash"><span></span>  R -e <span class="s2">&quot;install.packages(&#39;ggplot2&#39;, repos = &#39;http://cran.us.r-project.org&#39;)&quot;</span>
+</code></pre></div>
+<ul>
+<li>Other visualization libraries: </li>
+</ul>
+<div class="highlight"><pre><code class="language-bash" data-lang="bash"><span></span>  R -e <span class="s2">&quot;install.packages(c(&#39;devtools&#39;,&#39;mplot&#39;, &#39;googleVis&#39;), repos = &#39;http://cran.us.r-project.org&#39;); </span>
+<span class="s2">  require(devtools); install_github(&#39;ramnathv/rCharts&#39;)&quot;</span>
+</code></pre></div>
+<p>We recommend you to also install the following optional R libraries for happy data analytics:</p>
+
+<ul>
+<li>glmnet</li>
+<li>pROC</li>
+<li>data.table</li>
+<li>caret</li>
+<li>sqldf</li>
+<li>wordcloud</li>
+</ul>
+
+<h2>Configuration</h2>
+
+<p>To run Zeppelin with the R Interpreter, the <code>SPARK_HOME</code> environment variable must be set. The best way to do this is by editing <code>conf/zeppelin-env.sh</code>.
+If it is not set, the R Interpreter will not be able to interface with Spark.</p>
+
+<p>You should also copy <code>conf/zeppelin-site.xml.template</code> to <code>conf/zeppelin-site.xml</code>. That will ensure that Zeppelin sees the R Interpreter the first time it starts up.</p>
+
+<h2>Using the R Interpreter</h2>
+
+<p>By default, the R Interpreter appears as two Zeppelin Interpreters, <code>%r</code> and <code>%knitr</code>.</p>
+
+<p><code>%r</code> will behave like an ordinary REPL.  You can execute commands as in the CLI.   </p>
+
+<p><img class="img-responsive" src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/repl2plus2.png" width="700px"/></p>
+
+<p>R base plotting is fully supported</p>
+
+<p><img class="img-responsive" src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/replhist.png" width="550px"/></p>
+
+<p>If you return a data.frame, Zeppelin will attempt to display it using Zeppelin&#39;s built-in visualizations.</p>
+
+<p><img class="img-responsive" src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/replhead.png" width="550px"/></p>
+
+<p><code>%knitr</code> interfaces directly against <code>knitr</code>, with chunk options on the first line:</p>
+
+<p><img class="img-responsive" src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/knitgeo.png" width="550px"/></p>
+
+<p><img class="img-responsive" src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/knitstock.png" width="550px"/></p>
+
+<p><img class="img-responsive" src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/knitmotion.png" width="550px"/></p>
+
+<p>The two interpreters share the same environment.  If you define a variable from <code>%r</code>, it will be within-scope if you then make a call using <code>knitr</code>.</p>
+
+<h2>Using SparkR &amp; Moving Between Languages</h2>
+
+<p>If <code>SPARK_HOME</code> is set, the <code>SparkR</code> package will be loaded automatically:</p>
+
+<p><img class="img-responsive" src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/sparkrfaithful.png" width="550px"/></p>
+
+<p>The Spark Context and SQL Context are created and injected into the local environment automatically as <code>sc</code> and <code>sql</code>.</p>
+
+<p>The same context are shared with the <code>%spark</code>, <code>%sql</code> and <code>%pyspark</code> interpreters:</p>
+
+<p><img class="img-responsive" src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/backtoscala.png" width="700px"/></p>
+
+<p>You can also make an ordinary R variable accessible in scala and Python:</p>
+
+<p><img class="img-responsive" src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/varr1.png" width="550px"/></p>
+
+<p>And vice versa:</p>
+
+<p><img class="img-responsive" src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/varscala.png" width="550px"/></p>
+
+<p><img class="img-responsive" src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/varr2.png" width="550px"/></p>
+
+<h2>Caveats &amp; Troubleshooting</h2>
+
+<ul>
+<li><p>Almost all issues with the R interpreter turned out to be caused by an incorrectly set <code>SPARK_HOME</code>.  The R interpreter must load a version of the <code>SparkR</code> package that matches the running version of Spark, and it does this by searching <code>SPARK_HOME</code>. If Zeppelin isn&#39;t configured to interface with Spark in <code>SPARK_HOME</code>, the R interpreter will not be able to connect to Spark.</p></li>
+<li><p>The <code>knitr</code> environment is persistent. If you run a chunk from Zeppelin that changes a variable, then run the same chunk again, the variable has already been changed.  Use immutable variables.</p></li>
+<li><p>(Note that <code>%spark.r</code> and <code>%r</code> are two different ways of calling the same interpreter, as are <code>%spark.knitr</code> and <code>%knitr</code>. By default, Zeppelin puts the R interpreters in the <code>%spark.</code> Interpreter Group.</p></li>
+<li><p>Using the <code>%r</code> interpreter, if you return a data.frame, HTML, or an image, it will dominate the result. So if you execute three commands, and one is <code>hist()</code>, all you will see is the histogram, not the results of the other commands. This is a Zeppelin limitation.</p></li>
+<li><p>If you return a data.frame (for instance, from calling <code>head()</code>) from the <code>%spark.r</code> interpreter, it will be parsed by Zeppelin&#39;s built-in data visualization system.  </p></li>
+<li><p>Why <code>knitr</code> Instead of <code>rmarkdown</code>?  Why no <code>htmlwidgets</code>?  In order to support <code>htmlwidgets</code>, which has indirect dependencies, <code>rmarkdown</code> uses <code>pandoc</code>, which requires writing to and reading from disc.  This makes it many times slower than <code>knitr</code>, which can operate entirely in RAM.</p></li>
+<li><p>Why no <code>ggvis</code> or <code>shiny</code>?  Supporting <code>shiny</code> would require integrating a reverse-proxy into Zeppelin, which is a task.</p></li>
+<li><p>Max OS X &amp; case-insensitive filesystem.  If you try to install on a case-insensitive filesystem, which is the Mac OS X default, maven can unintentionally delete the install directory because <code>r</code> and <code>R</code> become the same subdirectory.</p></li>
+<li><p>Error <code>unable to start device X11</code> with the repl interpreter.  Check your shell login scripts to see if they are adjusting the <code>DISPLAY</code> environment variable.  This is common on some operating systems as a workaround for ssh issues, but can interfere with R plotting.</p></li>
+<li><p>akka Library Version or <code>TTransport</code> errors.  This can happen if you try to run Zeppelin with a SPARK_HOME that has a version of Spark other than the one specified with <code>-Pspark-1.x</code> when Zeppelin was compiled.</p></li>

+<h1>SAP BusinessObjects (Universe) Interpreter for Apache Zeppelin</h1>
+
+<div id="toc"></div>
+
+<h2>Overview</h2>
+
+<p><a href="https://help.sap.com/viewer/p/SAP_BUSINESSOBJECTS_BUSINESS_INTELLIGENCE_PLATFORM">SAP BusinessObjects BI platform (universes)</a> can simplify the lives of business users and IT staff. SAP BusinessObjects is based on universes. The universe contains dual-semantic layer model. The users make queries upon universes. This interpreter is new interface for universes.</p>
+
+<p><em>Disclaimer</em> SAP interpreter is not official interpreter for SAP BusinessObjects BI platform. It uses <a href="https://help.sap.com/viewer/5431204882b44fc98d56bd752e69f132/4.2.5/en-US/ec54808e6fdb101497906a7cb0e91070.html">BI Semantic Layer REST API</a></p>
+
+<p>This interpreter is not directly supported by SAP AG.</p>
+
+<p>Tested with versions 4.2SP3 (14.2.3.2220) and 4.2SP5. There is no support for filters in UNX-universes converted from old UNV format.</p>
+
+<p>The universe name must be unique.</p>
+
+<h2>Configuring SAP Universe Interpreter</h2>
+
+<p>At the &quot;Interpreters&quot; menu, you can edit SAP interpreter or create new one. Zeppelin provides these properties for SAP.</p>
+
+<table class="table-configuration">
+  <tr>
+    <th>Property Name</th>
+    <th>Value</th>
+    <th>Description</th>
+  </tr>
+  <tr>
+    <td>universe.api.url</td>
+    <td>http://localhost:6405/biprws</td>
+    <td>The base url for the SAP BusinessObjects BI platform. You have to edit "localhost" that you may use (ex. http://0.0.0.0:6405/biprws)</td>
+  </tr>
+  <tr>
+    <td>universe.authType</td>
+    <td>secEnterprise</td>
+    <td>The type of authentication for API of Universe. Available values: secEnterprise, secLDAP, secWinAD, secSAPR3</td>
+  </tr>
+  <tr>
+    <td>universe.password</td>
+    <td></td>
+    <td>The BI platform user password</td>
+  </tr>
+  <tr>
+    <td>universe.user</td>
+    <td>Administrator</td>
+    <td>The BI platform user login</td>
+  </tr>
+</table>

+
+<h3>How to use</h3>
+
+<p><li> Choose the universe
+<li> Choose dimensions and measures in <code>select</code> statement
+<li> Define conditions in <code>where</code> statement
+You can compare two dimensions/measures or use Filter (without value). 
+Dimesions/Measures can be compared with static values, may be <code>is null</code> or <code>is not null</code>, contains or not in list.
+Available the nested conditions (using braces &quot;()&quot;). &quot;and&quot; operator have more priority than &quot;or&quot;. </p>
+
+<p>If generated query contains promtps, then promtps will appear as dynamic form after paragraph submitting.</p>
+
+<p>Example query</p>
+<div class="highlight"><pre><code class="language-sql" data-lang="sql"><span></span><span class="o">%</span><span class="n">sap</span>
+
+<span class="n">universe</span> <span class="p">[</span><span class="n">Universe</span> <span class="n">Name</span><span class="p">];</span>

+</code></pre></div>
+<p>&lt;&lt;&lt;&lt;&lt;&lt;&lt; HEAD</p>
+
+<h3><code>distinct</code> keyword</h3>
+
+<p>You can write keyword <code>distinct</code> after keyword <code>select</code> to return only distinct (different) values.</p>
+
+<p>Example query
+```sql
+%sap
+universe [Universe Name];</p>
+
+<p>select distinct
+  [Folder1].[Dimension2], [Measure1]
+where
+  [Filter1];
+```</p>
+
+<h3><code>limit</code> keyword</h3>
+
+<p>You can write keyword <code>limit</code> and limit value in the end of query to limit the number of records returned based on a limit value.</p>
+
+<p>Example query
+```sql
+%sap
+universe [Universe Name];</p>
+
+<p>select
+  [Folder1].[Dimension2], [Measure1]
+where
+  [Filter1]
+limit 100;
+```</p>
+
+<h2>Object Interpolation</h2>
+
+<p>The SAP interpreter also supports interpolation of <code>ZeppelinContext</code> objects into the paragraph text.
+To enable this feature set <code>universe.interpolation</code> to <code>true</code>. The following example shows one use of this facility:</p>
+
+<h4>In Scala cell:</h4>
+<div class="highlight"><pre><code class="language-scala" data-lang="scala"><span></span><span class="n">z</span><span class="o">.</span><span class="n">put</span><span class="o">(</span><span class="s">&quot;curr_date&quot;</span><span class="o">,</span> <span class="s">&quot;2018-01-01 00:00:00&quot;</span><span class="o">)</span>
+</code></pre></div>
+<h4>In later SAP cell:</h4>
+<div class="highlight"><pre><code class="language-sql" data-lang="sql"><span></span><span class="k">where</span>
+   <span class="p">[</span><span class="n">Filter1</span><span class="p">]</span>

+<h1>Scalding Interpreter for Apache Zeppelin</h1>
+
+<div id="toc"></div>
+
+<p><a href="https://github.com/twitter/scalding">Scalding</a> is an open source Scala library for writing MapReduce jobs.</p>
+
+<h2>Building the Scalding Interpreter</h2>
+
+<p>You have to first build the Scalding interpreter by enable the <strong>scalding</strong> profile as follows:</p>
+<div class="highlight"><pre><code class="language-bash" data-lang="bash"><span></span>mvn clean package -Pscalding -DskipTests
+</code></pre></div>
+<h2>Enabling the Scalding Interpreter</h2>
+
+<p>In a notebook, to enable the <strong>Scalding</strong> interpreter, click on the <strong>Gear</strong> icon,select <strong>Scalding</strong>, and hit <strong>Save</strong>.</p>
+
+<p><center></p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/scalding-InterpreterBinding.png" alt="Interpreter Binding"></p>
+
+<p><img src="/docs/0.8.0/assets/themes/zeppelin/img/docs-img/scalding-InterpreterSelection.png" alt="Interpreter Selection"></p>
+
+<p></center></p>
+
+<h2>Configuring the Interpreter</h2>
+
+<p>Scalding interpreter runs in two modes:</p>
+
+<ul>
+<li>local</li>
+<li>hdfs</li>
+</ul>
+
+<p>In the local mode, you can access files on the local server and scalding transformation are done locally.</p>
+
+<p>In hdfs mode you can access files in HDFS and scalding transformation are run as hadoop map-reduce jobs.</p>
+
+<p>Zeppelin comes with a pre-configured Scalding interpreter in local mode.</p>
+
+<p>To run the scalding interpreter in the hdfs mode you have to do the following:</p>
+
+<p><strong>Set the classpath with ZEPPELIN_CLASSPATH_OVERRIDES</strong></p>
+
+<p>In conf/zeppelin<em>env.sh, you have to set
+ZEPPELIN</em>CLASSPATH_OVERRIDES to the contents of &#39;hadoop classpath&#39;
+and directories with custom jar files you need for your scalding commands.</p>
+
+<p><strong>Set arguments to the scalding repl</strong></p>
+
+<p>The default arguments are: <code>--local --repl</code></p>
+
+<p>For hdfs mode you need to add: <code>--hdfs --repl</code></p>
+
+<p>If you want to add custom jars, you need to add: <code>-libjars directory/*:directory/*</code></p>
+
+<p>For reducer estimation, you need to add something like:
+<code>-Dscalding.reducer.estimator.classes=com.twitter.scalding.reducer_estimation.InputSizeReducerEstimator</code></p>
+
+<p><strong>Set max.open.instances</strong></p>
+
+<p>If you want to control the maximum number of open interpreters, you have to select &quot;scoped&quot; interpreter for note
+option and set <code>max.open.instances</code> argument.</p>
+
+<h2>Testing the Interpreter</h2>
+
+<h3>Local mode</h3>
+
+<p>In example, by using the <a href="https://gist.github.com/johnynek/a47699caa62f4f38a3e2">Alice in Wonderland</a> tutorial, 
+we will count words (of course!), and plot a graph of the top 10 words in the book.</p>

+<h2>Future Work</h2>
+
+<ul>
+<li>Better user feedback (hadoop url, progress updates)</li>
+<li>Ability to cancel jobs</li>
+<li>Ability to dynamically load jars without restarting the interpreter</li>
+<li>Multiuser scalability (run scalding interpreters on different servers)</li>
+</ul>
