Apache Spark reassigned SPARK-23472:
------------------------------------
Assignee: (was: Apache Spark)
> Add config properties for administrator JVM options
> ---------------------------------------------------
>
> Key: SPARK-23472
> URL: https://issues.apache.org/jira/browse/SPARK-23472
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.3.0
> Reporter: Ryan Blue
> Priority: Major
>
> In our environment, users may need to add JVM options to their Spark
> applications (e.g. to override log configuration). They typically use
> {{--driver-java-options}} or {{spark.executor.extraJavaOptions}}. Both set
> extraJavaOptions properties. We also have a set of administrator JVM options
> to apply that set the garbage collector (G1GC) and kill the driver JVM on OOM.
> These two use cases both need to set extraJavaOptions properties, but will
> clobber one another. In the past we've maintained wrapper scripts, but this
> causes our default properties to be maintained in scripts rather than our
> spark-defaults.properties.
> I think we should add defaultJavaOptions properties that are added along with
> extraJavaOptions. Administrators could set defaultJavaOptions and these would
> always get added to the JVM command line, along with any user options instead
> of getting overwritten by user options.
