REM Spark interpreter configuration

REM Use provided spark installation
REM defining SPARK_HOME makes Zeppelin run spark interpreter process using spark-submit
REM
REM set SPARK_HOME                             REM (required) When it is defined, load it instead of Zeppelin embedded Spark libraries
REM set SPARK_SUBMIT_OPTIONS                   REM (optional) extra options to pass to spark submit. eg) "--driver-memory 512M --executor-memory 1G".
REM set SPARK_APP_NAME                         REM (optional) The name of spark application.

REM Use embedded spark binaries
REM without SPARK_HOME defined, Zeppelin still able to run spark interpreter process using embedded spark binaries.
REM however, it is not encouraged when you can define SPARK_HOME
REM
REM Options read in YARN client mode
REM set HADOOP_CONF_DIR                         REM yarn-site.xml is located in configuration directory in HADOOP_CONF_DIR.

REM set PYSPARK_PYTHON                          REM path to the python command. must be the same path on the driver(Zeppelin) and all workers.
