Hyukjin Kwon updated SPARK-22567:
---------------------------------
Labels: bulk-closed (was: )
> spark.mesos.executor.memoryOverhead equivalent for the Driver when running on
> Mesos
> -----------------------------------------------------------------------------------
>
> Key: SPARK-22567
> URL: https://issues.apache.org/jira/browse/SPARK-22567
> Project: Spark
> Issue Type: Improvement
> Components: Mesos
> Affects Versions: 2.2.0
> Reporter: Michael Moss
> Priority: Minor
> Labels: bulk-closed
>
> spark.mesos.executor.memoryOverhead is:
> "The amount of additional memory, specified in MB, to be allocated per
> executor. By default, the overhead will be larger of either 384 or 10% of
> spark.executor.memory"
> It is important for every JVM process to have memory available to it, beyond
> its heap (Xmx) for native allocations.
> When using the MesosClusterDispatcher and running the Driver on Mesos
> (https://spark.apache.org/docs/latest/running-on-mesos.html#cluster-mode), it
> appears that the Driver's mesos sandbox is allocated with the same amount of
> memory (configured with spark.driver.memory) as the heap (Xmx) itself. This
> increases the prevalence of OOM exceptions.
