Joseph E. Gonzalez commented on SPARK-1792:
-------------------------------------------
That makes a lot of sense! In that case perhaps the template should list more
options (e.g., how to enable kryo and disable/enable kryo reference tracking).
Also it might be helpful to print a message on launch of the spark-shell
stating that additional configuration options can be set in
conf/spark-defaults.conf.
> Missing Spark-Shell Configure Options
> -------------------------------------
>
> Key: SPARK-1792
> URL: https://issues.apache.org/jira/browse/SPARK-1792
> Project: Spark
> Issue Type: Bug
> Components: Documentation, Spark Core
> Reporter: Joseph E. Gonzalez
>
> The `conf/spark-env.sh.template` does not have configure options for the
> spark shell. For example to enable Kryo for GraphX when using the spark
> shell in stand alone mode it appears you must add:
> {code}
> SPARK_SUBMIT_OPTS="-Dspark.serializer=org.apache.spark.serializer.KryoSerializer
> "
> SPARK_SUBMIT_OPTS+="-Dspark.kryo.registrator=org.apache.spark.graphx.GraphKryoRegistrator
> "
> {code}
> However SPARK_SUBMIT_OPTS is not documented anywhere. Perhaps the
> spark-shell should have its own options (e.g., SPARK_SHELL_OPTS).
