i have a running job that i cancel while keeping the spark context alive. at the time of cancellation the active stage is 14.
i see in logs: 2014/03/04 16:43:19 INFO scheduler.DAGScheduler: Asked to cancel job group 3a25db23-2e39-4497-b7ab-b26b2a976f9c 2014/03/04 16:43:19 INFO scheduler.TaskSchedulerImpl: Cancelling stage 10 2014/03/04 16:43:19 INFO scheduler.TaskSchedulerImpl: Cancelling stage 14 2014/03/04 16:43:19 INFO scheduler.TaskSchedulerImpl: Stage 14 was cancelled 2014/03/04 16:43:19 INFO scheduler.TaskSchedulerImpl: Remove TaskSet 14.0 from pool x 2014/03/04 16:43:19 INFO scheduler.TaskSchedulerImpl: Cancelling stage 13 2014/03/04 16:43:19 INFO scheduler.TaskSchedulerImpl: Cancelling stage 12 2014/03/04 16:43:19 INFO scheduler.TaskSchedulerImpl: Cancelling stage 11 2014/03/04 16:43:19 INFO scheduler.TaskSchedulerImpl: Cancelling stage 15 so far it all looks good. then i get a lot of messages like this: 2014/03/04 16:43:20 INFO scheduler.TaskSchedulerImpl: Ignoring update with state FINISHED from TID 883 because its task set is gone 2014/03/04 16:43:24 INFO scheduler.TaskSchedulerImpl: Ignoring update with state KILLED from TID 888 because its task set is gone after this stage 14 hangs around in active stages, without any sign of progress or cancellation. it just sits there forever, stuck. looking at the logs of the executors confirms this. they task seem to be still running, but nothing is happening. for example (by the time i look at this its 4:58 so this tasks hasnt done anything in 15 mins): 14/03/04 16:43:16 INFO Executor: Serialized size of result for 943 is 1007 14/03/04 16:43:16 INFO Executor: Sending result for 943 directly to driver 14/03/04 16:43:16 INFO Executor: Finished task ID 943 14/03/04 16:43:16 INFO Executor: Serialized size of result for 945 is 1007 14/03/04 16:43:16 INFO Executor: Sending result for 945 directly to driver 14/03/04 16:43:16 INFO Executor: Finished task ID 945 14/03/04 16:43:19 INFO BlockManager: Removing RDD 66 not sure what to make of this. any suggestions? best, koert
