Hi, We have seen weird issues with CallableQueueService with oozie 3.3.2. We couldn't root-cause the exact code causing the issue, so not sure if its already fixed in 4.0. Any pointers will be helpful:
Materialisation for a coord just stops. CoordMaterializeTriggerService picks up that coord at every materialisation interval, but CoordMaterializeTransitionXCommand doesn't get called. Looks like CoordMaterializeTransitionXCommand is lost somewhere in the queue. Whenever this issue happens, the number of coords picked up for materialisation is 40-50 and we also see this log: oozie.log-2013-11-08-01:2013-11-08 01:00:12,225 WARN CallableQueueService:542 - USER[-] GROUP[-] max concurrency for callable [#composite#coord_mater] exceeded, requeueing with [500]ms delay Restarting oozie resumes materialization. Looks like materialisation batch size is 50, and in callable queue service, composite callable batch size is set to 10, and max concurrency is 3. So, when there are more than 30 coords picked for materialisation, the 4th/5th batch of coords is magically lost somewhere. Code looks fine and don't know where the leak is. Tried re-producing this in local machine by tuning these configs, but couldn't get anything Thanks, Shwetha -- _____________________________________________________________ The information contained in this communication is intended solely for the use of the individual or entity to whom it is addressed and others authorized to receive it.
