Thomas Graves updated SPARK-12384:
----------------------------------
Assignee: Dhruve Ashar
> Allow -Xms to be set differently then -Xmx
> ------------------------------------------
>
> Key: SPARK-12384
> URL: https://issues.apache.org/jira/browse/SPARK-12384
> Project: Spark
> Issue Type: Improvement
> Components: Spark Submit, YARN
> Affects Versions: 1.6.0
> Reporter: Thomas Graves
> Assignee: Dhruve Ashar
> Priority: Minor
>
> Currently Spark automatically sets the -Xms parameter to be the same as the
> -Xmx parameter. We should allow the user to set this separately.
> The main use case here is if I'm running the spark-shell on a shared gateway.
> Many users specify a larger memory size then needed and will never use that
> much memory, so all its doing is preventing other users from potentially
> using that memory. Allowing it to be less is just more multi-tenant friendly.
> I think it makes sense to leave this for cluster mode, although if a user
> really wants to override I don't see why we shouldn't let them.
