> Affects Versions: 1.3.0, 1.3.1
> Environment: spark 1.3.1
> Reporter: Tao Li
> Assignee: Josh Rosen
> Priority: Critical
> Labels: Bug, Core, DAGScheduler, OOM, Streaming

>
> I am using spark streaming(1.3.1) as a long time running service and out of
> memory after running for 7 days.
> I found that the field authorizedCommittersByStage in OutputCommitCoordinator
> class cause the OOM.
> authorizedCommittersByStage is a map, key is StageId, value is
> Map[PartitionId, TaskAttemptId]. The OutputCommitCoordinator class has a
> method stageEnd which will remove stageId from authorizedCommittersByStage.
> But the method stageEnd is never called by DAGSchedule. And it cause the
> authorizedCommittersByStage's stage info never be cleaned, which cause OOM.
> It happens in my spark streaming program(1.3.1), I am not sure if it will
> appear in other spark components and other spark version.
