Zhang, Liye commented on SPARK-9111:
------------------------------------
Hi [~srowen], the memory dump mentioned here is about the spark memory usage,
which is related with umbrella
[SPARK-9103|https://issues.apache.org/jira/browse/SPARK-9103], not the
HeapDump, since we want to know what is the memory status for different spark
component. It's not easy to get how much memory used for a specific spark
component directly from the HeapDump, right?
> Dumping the memory info when an executor dies abnormally

> Key: SPARK-9111
> URL: https://issues.apache.org/jira/browse/SPARK-9111
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Reporter: Zhang, Liye
> Priority: Minor
>
> When an executor is not normally finished, we shall give out it's memory dump
> info right before the JVM shutting down. So that if the executor is killed
> because of OOM, we can easily checkout how is the memory used and which part
> cause the OOM.
