Component/s: Mesos
> Support launching multiple mesos executors in coarse grained mesos mode
> -----------------------------------------------------------------------
>
> Key: SPARK-5095
> URL: https://issues.apache.org/jira/browse/SPARK-5095
> Project: Spark
> Issue Type: Improvement
> Components: Mesos
> Reporter: Timothy Chen
>
> Currently in coarse grained mesos mode, it's expected that we only launch one Mesos executor that launches one JVM process to launch multiple spark executors.
> However, this become a problem when the JVM process launched is larger than an ideal size (30gb is recommended value from databricks), which causes GC problems reported on the mailing list.
> We should support launching mulitple executors when large enough resources are available for spark to use, and these resources are still under the configured limit.
