Assignee: (was: Juan Yu)
> impala components with embedded JVM should exit, produce heap dump on OOM
> -------------------------------------------------------------------------
>
> Key: IMPALA-1956
> URL: https://issues.apache.org/jira/browse/IMPALA-1956
> Project: IMPALA
> Issue Type: Improvement
> Components: Frontend
> Affects Versions: Impala 2.1.1, Impala 2.2
> Reporter: Chris Leroy
> Priority: Minor
> Labels: ramp-up, supportability
>
> I believe a number of Impala components embed a JVM. If an OOM occurs in java
> code running in that JVM, it would be nice if a heap dump was produced and
> the Impala component could be configured to exit. Basically if we could have
> the equivalent of "-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/tmp
> -XX:OnOutOfMemoryError=kill -9 %p". This is on the presumption that the OOM
> leaves the JVM in particular and the Impala component in general in an
> unusable state.
