This interpreter provides all capabilities of Apache HBase shell within Apache Zeppelin. The interpreter assumes that Apache HBase client software has been installed and it can connect to the Apache HBase cluster from the machine on where Apache Zeppelin is installed.To get start with HBase, please see HBase Quickstart.HBase relea se supportedBy default, Zeppelin is built against HBase 1.0.x releases. To work with HBase 1.1.x releases, use the following build command:# HBase 1.1.4mvn clean package -DskipTests -Phadoop-2.6 -Dhadoop.version=2.6.0 -P build-distr -Dhbase.hbase.version=1.1.4 -Dhbase.hadoop.version=2.6.0To work with HBase 1.2.0+, use the following build command:# HBase 1.2.0mvn clean package -DskipTests -Phadoop-2.6 -Dhadoop.version=2.6.0 -P build-distr -Dhbase.hbase.version=1.2.0 -Dhbase.hadoop.version=2.6.0Configuration Property Default Description hbase.home /usr/lib/hbase Installation directory of HBase, defaults to HBASE_HOME in environment hbase.ruby.sources lib/ruby Path to Ruby scripts relative to 'hbase.home' zeppelin.hbase.test.mode false Disable checks for unit and manual tests If you want to connect to HBase running on a cluster, you&#39;ll need to follow the next step.Export HBASE_HOMEIn conf/zeppelin-env.sh, export HBASE_H OME environment variable with your HBase installation path.

The value may vary depending on your Spark cluster deployment type.For example,local[*] in local modespark://master:7077 in standalone clusteryarn-client in Yarn client modemesos://host:5050 in Mesos clusterThat&#39;s it. Zeppelin will work with any version of Spark and any deployment type without rebuilding Zeppelin in this way. For the further information about Spark &amp; Zeppelin version compatibility, please refer to &quot;Available Interpreters&quot; section in Zeppelin download page.Note that without exporting SPARK_HOME, it&#39;s running in local mode with included version of Spark. The included version may vary depending on the build profile.SparkContext, SQLContext, SparkSession, ZeppelinContextSparkContext, SQLContext and ZeppelinContext are automatically created and exposed as variable names sc, sqlContext and z, respectively, in Scala, Python and R environments.Starin g from 0.6.1 SparkSession is available as variable spark when you are using Spark 2.x.Note that Scala/Python/R environment shares the same SparkContext, SQLContext and ZeppelinContext instance. Dependency ManagementThere are two ways to load external libraries in Spark interpreter. First is using interpreter setting menu and second is loading Spark properties.1. Setting Dependencies via Interpreter SettingPlease see Dependency Management for the details.2. Loading Spark PropertiesOnce SPARK_HOME is set in conf/zeppelin-env.sh, Zeppelin uses spark-submit as spark interpreter runner. spark-submit supports two ways to load configurations. The first is command line options such as --master and Zeppelin can pass these options to spark-submit by exporting SPARK_SUBMIT_OPTIONS in conf/zeppelin-env.sh. Second is reading configuration options from SPARK_HOME/conf/spark-defaults.conf.

ZeppelinContext provides some additional functions and utilities.Object ExchangeZeppelinContext extends map and it&#39;s shared between Scala and Python environment.So you can put some objects from Scala and read it from Python, vice versa. // Put object from scala%sparkval myObject = ...z.put(&quot;objName&quot;, myObject)// Exchanging data framesmyScalaDataFrame = ...z.put(&quot;myScalaDataFrame&quot;, myScalaDataFrame)val myPythonDataFrame = z.get(&quot;myPythonDataFrame&quot;).asInstanceOf[DataFrame] # Get object from python%spark.pysparkmyObject = z.get(&quot;objName&quot;)# Exchanging data framesmyPythonDataFrame = ...z.put(&quot;myPythonDataFrame&a mp;quot;, postsDf._jdf)myScalaDataFrame = DataFrame(z.get(&quot;myScalaDataFrame&quot;), sqlContext) Form CreationZeppelinContext provides functions for creating forms.In Scala and Python environments, you can create forms programmatically. %spark/* Create text input form */z.input(&quot;formName&quot;)/* Create text input form with default value */z.input(&quot;formName&quot;, &quot;defaultValue&quot;)/* Create select form */z.select(&quot;formName&quot;, Seq((&quot;option1&quot;, &quot;option1DisplayName&quot;), (&quot;option2&quot;, &quot;option2DisplayName&quot;)))/* Create select form with default value*/z.select(&quot;formName&quot;, &quot;option1&quot;, Seq((&quot;option1&quot;, &quot;option1DisplayName&quot;), (&quot;option2&quot;, &quot;option2DisplayName&quot;))) %spark.pyspark# Create text i nput formz.input(&quot;formName&quot;)# Create text input form with default valuez.input(&quot;formName&quot;, &quot;defaultValue&quot;)# Create select formz.select(&quot;formName&quot;, [(&quot;option1&quot;, &quot;option1DisplayName&quot;), (&quot;option2&quot;, &quot;option2DisplayName&quot;)])# Create select form with default valuez.select(&quot;formName&quot;, [(&quot;option1&quot;, &quot;option1DisplayName&quot;), (&quot;option2&quot;, &quot;option2DisplayName&quot;)], &quot;option1&quot;) In sql environment, you can create form in simple template.%spark.sqlselect * from ${table=defaultTableName} where text like &#39;%${search}%&#39;To learn more about dynamic form, checkout Dynamic Form.Matplotlib Integration (pyspark)Both the python and pyspark interpreters have built-in support for inline visualization using matpl otlib, a popular plotting library for python. More details can be found in the python interpreter documentation, since matplotlib support is identical. More advanced interactive plotting can be done with pyspark through utilizing Zeppelin&#39;s built-in Angular Display System, as shown below:Interpreter setting optionYou can choose one of shared, scoped and isolated options wheh you configure Spark interpreter. Spark interpreter creates separated Scala compiler per each notebook but share a single SparkContext in scoped mode (experimental). It creates separated SparkContext per each notebook in isolated mode.Setting up Zeppelin with KerberosLogical setup with Zeppelin, Kerberos Key Distribution Center (KDC), and Spark on YARN:Configuration SetupOn the server that Zeppelin is installed, install Kerberos client modules and configuration, krb5.conf.This is to make the server communicate with KDC.Set SPARK_HOME in [ZEPPELIN_HOME]/conf/zeppelin-env.sh to use spark-submit(Additionally , you might have to set export HADOOP_CONF_DIR=/etc/hadoop/conf)Add the two properties below to Spark configuration ([SPARK_HOME]/conf/spark-defaults.conf):spark.yarn.principalspark.yarn.keytabNOTE: If you do not have permission to access for the above spark-defaults.conf file, optionally, you can add the above lines to the Spark Interpreter setting through the Interpreter tab in the Zeppelin UI.That&#39;s it.

ZeppelinContext provides some additional functions and utilities.Object ExchangeZeppelinContext extends map and it&#39;s shared between Scala and Python environment.So you can put some objects from Scala and read it from Python, vice versa. // Put object from scala%sparkval myObject = ...z.put(&quot;objName&quot;, myObject)// Exchanging data framesmyScalaDataFrame = ...z.put(&quot;myScalaDataFrame&quot;, myScalaDataFrame)val myPythonDataFrame = z.get(&quot;myPythonDataFrame&quot;).asInstanceOf[DataFrame] # Get object from python%spark.pysparkmyO bject = z.get(&quot;objName&quot;)# Exchanging data framesmyPythonDataFrame = ...z.put(&quot;myPythonDataFrame&quot;, postsDf._jdf)myScalaDataFrame = DataFrame(z.get(&quot;myScalaDataFrame&quot;), sqlContext) Form CreationZeppelinContext provides functions for creating forms.In Scala and Python environments, you can create forms programmatically. %spark/* Create text input form */z.input(&quot;formName&quot;)/* Create text input form with default value */z.input(&quot;formName&quot;, &quot;defaultValue&quot;)/* Create select form */z.select(&quot;formName&quot;, Seq((&quot;option1&quot;, &quot;option1DisplayName&quot;), (&quot;option2&quot;, &quot;option2DisplayName&quot;)))/* Create select form with default value*/z.select(&quot;formName&quot;, &quot;option1&quot;, Seq((&quot;option1&quot;, &quot;option1DisplayName&quot;), (&quot;option2&quot;, &quot;option2DisplayName&quot;))) %spark.pyspark# Create text input formz.input(&quot;formName&quot;)# Create text input form with default valuez.input(&quot;formName&quot;, &quot;defaultValue&quot;)# Create select formz.select(&quot;formName&quot;, [(&quot;option1&quot;, &quot;option1DisplayName&quot;), (&quot;option2&quot;, &quot;option2DisplayName&quot;)])# Create select form with default valuez.select(&quot;formName&quot;, [(&quot;option1&quot;, &quot;option1DisplayName&quot;), (&quot;option2&quot;, &quot;option2DisplayName&quot;)], &quot;option1&quot;) In sql environment, you can create form in simple template.%spark.sqlselect * from ${table=defaultTableName} where text like &#39;%${search}%&#39;To learn more about dynamic form, checkout Dynamic Form.Matplot lib Integration (pyspark)Both the python and pyspark interpreters have built-in support for inline visualization using matplotlib, a popular plotting library for python. More details can be found in the python interpreter documentation, since matplotlib support is identical. More advanced interactive plotting can be done with pyspark through utilizing Zeppelin&#39;s built-in Angular Display System, as shown below:Interpreter setting optionYou can choose one of shared, scoped and isolated options wheh you configure Spark interpreter. Spark interpreter creates separated Scala compiler per each notebook but share a single SparkContext in scoped mode (experimental). It creates separated SparkContext per each notebook in isolated mode.Setting up Zeppelin with KerberosLogical setup with Zeppelin, Kerberos Key Distribution Center (KDC), and Spark on YARN:Configuration SetupOn the server that Zeppelin is installed, install Kerberos client modules and configuration, krb5.conf.This is to make the server communicate with KDC.Set SPARK_HOME in [ZEPPELIN_HOME]/conf/zeppelin-env.sh to use spark-submit(Additionally, you might have to set export HADOOP_CONF_DIR=/etc/hadoop/conf)Add the two properties below to Spark configuration ([SPARK_HOME]/conf/spark-defaults.conf):spark.yarn.principalspark.yarn.keytabNOTE: If you do not have permission to access for the above spark-defaults.conf file, optionally, you can add the above lines to the Spark Interpreter setting through the Interpreter tab in the Zeppelin UI.That&#39;s it.
