Zeppelin

Zeppelin is uncompressed in /opt/zeppelin.

The boot.sh accepts the following parameters:

boot.sh node_type action cluster_name

And the following environment variables for zeppelin configuration:

export ZEPPELIN_PORT=${ZEPPELIN_PORT:-8080}
export ZEPPELIN_NOTEBOOK_DIR=${ZEPPELIN_NOTEBOOK_DIR:-/data}
export ZEPPELIN_NOTEBOOK_PUBLIC=${ZEPPELIN_NOTEBOOK_PUBLIC:-false}

The default configuration for Zeppelin, Spark interpreter, Alluxio and HDFS can be found in interpreter.json, spark-defaults.conf, alluxio-site.properties, hdfs-site.xml and core-site.xml respectively.

**NOTE:**The interpreter needs to have the spark/eventlogs folder created in HDFS before the first job is executed or the interpreter will crash.

NOTE: The current image includes its default configuration in the "interpreters.json" file. In order to run zeppelin jobs in a local environment (minishift), spark.executor.memory property must be set accordingly to the memory assigned to each worker, the default value is 1g if not modified.

Version 1.2.0 of alluxio is needed in order to work with the combination of libraries the version 0.7.1 of zeppelin ships by default. If you need a newer version, you will need to build your own zeppelin distribution and docker image
