#### Spark interpreter configuration ####

## Use provided spark installation ##
## defining SPARK_HOME makes Zeppelin run spark interpreter process using spark-submit
##
export SPARK_HOME=/home/ec2-user/prereqs/spark-1.5.2-bin-hadoop2.6 
# export SPARK_SUBMIT_OPTIONS                   # (optional) extra options to pass to spark submit. eg) "--driver-memory 512M --executor-memory 1G".

## Use embedded spark binaries ##
## without SPARK_HOME defined, Zeppelin still able to run spark interpreter process using embedded spark binaries.
## however, it is not encouraged when you can define SPARK_HOME
##
# Options read in YARN client mode
# export HADOOP_CONF_DIR         		# yarn-site.xml is located in configuration directory in HADOOP_CONF_DIR.
# Pyspark (supported with Spark 1.2.1 and above)
# To configure pyspark, you need to set spark distribution's path to 'spark.home' property in Interpreter setting screen in Zeppelin GUI
# export PYSPARK_PYTHON          		# path to the python command. must be the same path on the driver(Zeppelin) and all workers.
# export PYTHONPATH  

## Spark interpreter options ##
##
# export ZEPPELIN_SPARK_USEHIVECONTEXT  # Use HiveContext instead of SQLContext if set true. true by default.
# export ZEPPELIN_SPARK_CONCURRENTSQL   # Execute multiple SQL concurrently if set true. false by default.
# export ZEPPELIN_SPARK_MAXRESULT       # Max number of SparkSQL result to display. 1000 by default.
