Dongjoon Hyun updated SPARK-38194:
----------------------------------
Component/s: Kubernetes
Mesos
> Make memory overhead factor configurable
> ----------------------------------------
>
> Key: SPARK-38194
> URL: https://issues.apache.org/jira/browse/SPARK-38194
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes, Mesos, YARN
> Affects Versions: 3.4.0
> Reporter: Adam Binford
> Assignee: Adam Binford
> Priority: Major
> Fix For: 3.4.0
>
>
> Currently if the memory overhead is not provided for a Yarn job, it defaults
> to 10% of the respective driver/executor memory. This 10% is hard-coded and
> the only way to increase memory overhead is to set the exact memory overhead.
> We have seen more than 10% memory being used, and it would be helpful to be
> able to set the default overhead factor so that the overhead doesn't need to
> be pre-calculated for any driver/executor memory size.
