> Key: OOZIE-587
> URL: https://issues.apache.org/jira/browse/OOZIE-587
> Project: Oozie
> Issue Type: Bug
> Reporter: Virag Kothari
> Assignee: Virag Kothari
> Fix For: 3.2.0
>
>
> There are services which run at regular intervals (StatusTransitService) and
> loads all the coordinator actions of a job in memory. Also Kill, Suspend and
> Resume commands bring all the coordinators actions of a job in memory. When
> the user had a couple of coordinator jobs each with around 10,000 actions, it
> caused an out of memory issue.
> Solution:
> Only required actions should be brought (through better use of sql seleciton
> and projection operators). "Select *" clause should be avoided unless
> necessary.
