| <h1>Pig Interpreter for Apache Zeppelin</h1> |
| |
| <div id="toc"></div> |
| |
| <h2>Overview</h2> |
| |
| <p><a href="https://pig.apache.org/">Apache Pig</a> is a platform for analyzing large data sets that consists of |
| a high-level language for expressing data analysis programs, |
| coupled with infrastructure for evaluating these programs. |
| The salient property of Pig programs is that their structure is amenable to substantial parallelization, |
| which in turns enables them to handle very large data sets.</p> |
| |
| <h2>Supported interpreter type</h2> |
| |
| <ul> |
| <li><p><code>%pig.script</code> (default Pig interpreter, so you can use <code>%pig</code>)</p> |
| |
| <p><code>%pig.script</code> is like the Pig grunt shell. Anything you can run in Pig grunt shell can be run in <code>%pig.script</code> interpreter, it is used for running Pig script where you don’t need to visualize the data, it is suitable for data munging. </p></li> |
| <li><p><code>%pig.query</code></p> |
| |
| <p><code>%pig.query</code> is a little different compared with <code>%pig.script</code>. It is used for exploratory data analysis via Pig latin where you can leverage Zeppelin’s visualization ability. There're 2 minor differences in the last statement between <code>%pig.script</code> and <code>%pig.query</code></p> |
| |
| <ul> |
| <li>No pig alias in the last statement in <code>%pig.query</code> (read the examples below).</li> |
| <li>The last statement must be in single line in <code>%pig.query</code></li> |
| </ul></li> |
| </ul> |
| |
| <h2>How to use</h2> |
| |
| <h3>How to setup Pig execution modes.</h3> |
| |
| <ul> |
| <li><p>Local Mode</p> |
| |
| <p>Set <code>zeppelin.pig.execType</code> as <code>local</code>.</p></li> |
| <li><p>MapReduce Mode</p> |
| |
| <p>Set <code>zeppelin.pig.execType</code> as <code>mapreduce</code>. HADOOP_CONF_DIR needs to be specified in <code>ZEPPELIN_HOME/conf/zeppelin-env.sh</code>.</p></li> |
| <li><p>Tez Local Mode</p> |
| |
| <p>Only Tez 0.7 is supported. Set <code>zeppelin.pig.execType</code> as <code>tez_local</code>.</p></li> |
| <li><p>Tez Mode</p> |
| |
| <p>Only Tez 0.7 is supported. Set <code>zeppelin.pig.execType</code> as <code>tez</code>. HADOOP_CONF_DIR and TEZ_CONF_DIR needs to be specified in <code>ZEPPELIN_HOME/conf/zeppelin-env.sh</code>.</p></li> |
| <li><p>Spark Local Mode</p> |
| |
| <p>Only Spark 1.6.x is supported, by default it is Spark 1.6.3. Set <code>zeppelin.pig.execType</code> as <code>spark_local</code>.</p></li> |
| <li><p>Spark Mode</p> |
| |
| <p>Only Spark 1.6.x is supported, by default it is Spark 1.6.3. Set <code>zeppelin.pig.execType</code> as <code>spark</code>. For now, only yarn-client mode is supported. To enable it, you need to set property <code>SPARK_MASTER</code> to yarn-client and set <code>SPARK_JAR</code> to the spark assembly jar.</p></li> |
| </ul> |
| |
| <h3>How to choose custom Spark Version</h3> |
| |
| <p>By default, Pig Interpreter would use Spark 1.6.3 built with scala 2.10, if you want to use another spark version or scala version, |
| you need to rebuild Zeppelin by specifying the custom Spark version via -Dpig.spark.version=<custom_spark_version> and scala version via -Dpig.scala.version=<scala_version> in the maven build command.</p> |
| |
| <h3>How to configure interpreter</h3> |
| |
| <p>At the Interpreters menu, you have to create a new Pig interpreter. Pig interpreter has below properties by default. |
| And you can set any Pig properties here which will be passed to Pig engine. (like tez.queue.name & mapred.job.queue.name). |
| Besides, we use paragraph title as job name if it exists, else use the last line of Pig script. |
| So you can use that to find app running in YARN RM UI.</p> |

| <h3>Example</h3> |
| |
| <h5>pig</h5> |
| <div class="highlight"><pre><code class="text language-text" data-lang="text">%pig |
| |
| bankText = load 'bank.csv' using PigStorage(';'); |
| bank = foreach bankText generate $0 as age, $1 as job, $2 as marital, $3 as education, $5 as balance; |
| bank = filter bank by age != '"age"'; |
| bank = foreach bank generate (int)age, REPLACE(job,'"','') as job, REPLACE(marital, '"', '') as marital, (int)(REPLACE(balance, '"', '')) as balance; |
| store bank into 'clean_bank.csv' using PigStorage(';'); -- this statement is optional, it just show you that most of time %pig.script is used for data munging before querying the data. |
| </code></pre></div> |
| <h5>pig.query</h5> |
| |
| <p>Get the number of each age where age is less than 30</p> |
| <div class="highlight"><pre><code class="text language-text" data-lang="text">%pig.query |
| |
| bank_data = filter bank by age < 30; |
| b = group bank_data by age; |
| foreach b generate group, COUNT($1); |
| </code></pre></div> |
| <p>The same as above, but use dynamic text form so that use can specify the variable maxAge in textbox. |
| (See screenshot below). Dynamic form is a very cool feature of Zeppelin, you can refer this <a href="(../usage/dynamic_form/intro.html">link</a>) for details.</p> |
| <div class="highlight"><pre><code class="text language-text" data-lang="text">%pig.query |
| |
| bank_data = filter bank by age < ${maxAge=40}; |
| b = group bank_data by age; |
| foreach b generate group, COUNT($1) as count; |
| </code></pre></div> |
| <p>Get the number of each age for specific marital type, |
| also use dynamic form here. User can choose the marital type in the dropdown list (see screenshot below).</p> |
| <div class="highlight"><pre><code class="text language-text" data-lang="text">%pig.query |
| |
| bank_data = filter bank by marital=='${marital=single,single|divorced|married}'; |
| b = group bank_data by age; |
| foreach b generate group, COUNT($1) as count; |
| </code></pre></div> |
| <p>The above examples are in the Pig tutorial note in Zeppelin, you can check that for details. Here's the screenshot.</p> |

| |
| <p>Data is shared between <code>%pig</code> and <code>%pig.query</code>, so that you can do some common work in <code>%pig</code>, |
| and do different kinds of query based on the data of <code>%pig</code>. |
| Besides, we recommend you to specify alias explicitly so that the visualization can display |
| the column name correctly. In the above example 2 and 3 of <code>%pig.query</code>, we name <code>COUNT($1)</code> as <code>count</code>. |
| If you don't do this, then we will name it using position. |
| E.g. in the above first example of <code>%pig.query</code>, we will use <code>col_1</code> in chart to represent <code>COUNT($1)</code>.</p> |
