Now we will set up Zeppelin, which can run both Spark-Shell (in scala) and PySpark (in python) Spark jobs from its notebooks. We will build, run and configure Zeppelin to run the same Spark jobs in Scala and Python, using the Zeppelin SQL interpreter and Matplotlib to visualize SparkSQL query results. A comparison between Scala and Python. Note that scala / python environment shares the same SparkContext, SQLContext, ZeppelinContext instance. Dependency Management. There are two ways to load external library in spark interpreter. First is using Zeppelin's %dep interpreter and second is loading Spark properties. 1. Dynamic Dependency Loading via %dep interpreter Apache Zeppelin notebooks run on kernels and Spark engines. Apache Zeppelin supports many interpreters such as Scala, Python, and R. The Spark interpreter and Livy interpreter can also be set up to connect to a designated Spark or Livy service. By default, the Zeppelin Spark interpreter connects to the Spark that is local to the Zeppelin container In Zeppelin, an interpreter is a plugin that enables you to use a specific language/data-processing-backend. In our case, we will be using the %spark2 interpreter which allows us to program Spark using Scala. Open the Interpreter configuration page and search for the spark2 interpreter.

An Apache Zeppelin interpreter is a plugin that enables you to access processing engines and data sources from the Zeppelin UI. For example, if you want to use Python code in your Zeppelin notebook, you need a Python interpreter. Each interpreter runs in its own JVM on the same node as the Zeppelin server. The Zeppelin server communicates wit The interpreter is a plug-in, which enables Zeppelin to use a specific programming language - such as Scala or Python - or a data processing back-end, such as Spark, Pig or Frink. We have the Spark interpreter, which was the first one that was supported by Zeppelin. We have also had the Neo4j interpreter since version 0.8 org.scala-lang:scala-library,org.scala-lang:scala-reflect,org.scala-lang:scala-compiler org.apache.flink:flink-clients_2.11:1.4.2 And I have also changed the property host of the interpreter from local to jobmanager , with this change the Flink interpreter will access to the container inside our docker-compose, named as Jobmanager, instead of.
