> Remove min heap setting in Kubernetes Dockerfile entrypoint
> -----------------------------------------------------------
>
> Key: SPARK-40505
> URL: https://issues.apache.org/jira/browse/SPARK-40505
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes
> Affects Versions: 3.3.0, 3.2.2
> Reporter: Bryan Keller
> Priority: Major
>
> The entrypoint script for the Kubernetes Dockerfile sets the Java min heap
> setting (-Xms) to be the same as the max setting (-Xmx) for the executor
> process. This prevents the JVM from shrinking the heap and can lead to
> excessive memory usage in some scenarios. Removing the min heap setting is
> consistent with YARN executor startup.
