Hi Swetha, Was there any other warning message or requeuing message happened (pls check ooze.log)? Why the materialization batch size is 50? default is 10. right? Did you try to increase the concurrency value to 10 (for example)?
What is the value "queue.size"? It should show if the system was heavily loaded. What are the values for these props: oozie.service.CallableQueueService.queue.size oozie.service.CallableQueueService.threads oozie.service.coord.default.throttle Regards, Mohammad On Friday, November 8, 2013 6:42 PM, Shwetha GS <[email protected]> wrote: Oozie dev, did anyone get a chance to take a look at this > On 08-Nov-2013, at 6:08 pm, Shwetha GS <[email protected]> wrote: > > Hi, > > We have seen weird issues with CallableQueueService with oozie 3.3.2.
