Hyukjin Kwon resolved SPARK-25008.
----------------------------------
Resolution: Incomplete
> Add memory mode info to showMemoryUsage in TaskMemoryManager
> ------------------------------------------------------------
>
> Key: SPARK-25008
> URL: https://issues.apache.org/jira/browse/SPARK-25008
> Project: Spark
> Issue Type: Task
> Components: Spark Core
> Affects Versions: 2.3.0
> Reporter: Ankur Gupta
> Priority: Major
> Labels: bulk-closed
>
> TaskMemoryManager prints the current memory usage information before throwing
> an OOM exception which is helpful in debugging issues. This log does not have
> the memory mode information which can be also useful to quickly determine
> which memory users need to increase.
> This JIRA is to add that information to showMemoryUsage method of
> TaskMemoryManager.
> Current logs:
