In Zeppelin, at each row I am having to provide the interpreter at each row. Is there a way to set the interpreter for the whole session.

How do I set the interpreter for the whole session?

Answer 1

The Spark Interpreter group currently has 4 interpreter as listed here...

https://zeppelin.incubator.apache.org/docs/0.5.0-incubating/interpreter/spark.html

The default interpreter is %spark and default interpreter is selected based on the order of the interpreter listed in the zeppelin.interpreters property in zeppelin-site.xml config file.

The current order of interpreter in your zeppelin-site.xml (zeppelin.interpreters property) will be this ...

org.apache.zeppelin.spark.SparkInterpreter,org.apache.zeppelin.spark.PySparkInterpreter

Modify this to ...

org.apache.zeppelin.spark.PySparkInterpreter, org.apache.zeppelin.spark.SparkInterpreter

and restart Zeppelin (zeppelin-daemon.sh restart)

This will make %pyspark as default interpreter.

Thanks
