Bowen Zhang commented on OOZIE-1532:
------------------------------------

[~shwethags], purging coord children is enabled by users in oozie conf. By 
default, we keep the old behavior. So, users are aware of purge happening. And 
what do you mean by {quote}the action get should always return actions relative 
to coord beginning and not relative to the actions in db{quote}

> Purging should remove completed children job for long running coordinator jobs

> Specifically, this is for long running coordinator jobs with high frequency. 
> all child workflows are never purged as the coord job is still running.
> Oozie server configuration that indicates how many coordinator actions 
> frequency ticks to keep. By doing this it would be possible to purge running 
> coord jobs. By default this would not be enabled and the current logic would 
> remain.
