Andrew Purtell commented on BIGTOP-979:
---------------------------------------
The location where heap dumps are written should be configurable, specifiable
in /etc/defaults/$service, and should be disabled by default.
> Add hprof dump settings on OOM to all JVMs started by bigtop scripts
> --------------------------------------------------------------------

> Key: BIGTOP-979
> URL: https://issues.apache.org/jira/browse/BIGTOP-979
> Project: Bigtop
> Issue Type: Bug
> Components: Init scripts
> Reporter: Alejandro Abdelnur
>
> Run into the following while doing some troubleshooting:
> ------
> If you run your application with the VM flag -XX:+HeapDumpOnOutOfMemoryError
> a heap dump is written on the first Out Of Memory Error. There is no overhead
> involved unless a OOM actually occurs. This flag is a must for production
> systems as it is often the only way to further analyze the problem.
> ------
> IMO, it would be good if we get all startup scripts add this option to the
> java calls.
