I see a container request in the log with 2015-01-27 15:43:15,434 INFO [TaskSchedulerEventHandlerThread] rm.YarnTaskSchedulerService: Allocation request for task: attempt_1419300485749_371785_1_00_000000_0 with request: Capability[<memory:2867, vCores:3>]Priority[2] host: yhd-jqhadoop11.int.yihaodian.com rack: null ... 2015-01-27 15:43:17,635 INFO [DelayedContainerManager] rm.YarnTaskSchedulerService: Releasing held container as either there are pending but unmatched requests or this is not a session, containerId=container_1419300485749_371785_01_000002, pendingTasks=1, isSession=true. isNew=true That seems to indicate that a container allocation request was made, but YARN resource manager never responded with a container (or gave the wrong container?). Does the container size 2867 suggest any idea on what that might be? Cheers, Gopal
