Bowen Zhang commented on OOZIE-1532:
------------------------------------
[~shwethags], if you read my comment with [~sriksun], both coord action and
corresponding workflow objects are deleted during purging. So, C@1 is gone once
purged. I don't know how you can recover and retrieve a delete object. Do you
just return nothing if start=1 and len=10 and C@1-10 are all purged?
> 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.
