Vladislav Kuzemchik commented on SPARK-4906:
--------------------------------------------

Same thing with spark 1.6.

We recently migrated from 1.3.1 to 1.6.1.

Had to increase heap from 1G to 32G to at least have it running fir 2-3 days.

With streaming application it is constantly growing, so we have to restart 
streaming application once in a while.

Attached screenshot of 2G heap in JProfile.

> Spark master was OOMing with a lot of stack traces retained in 
> JobProgressListener. The object dependency goes like the following.
> JobProgressListener.stageIdToData => StageUIData.taskData => 
> TaskUIData.errorMessage
> Each error message is ~10kb since it has the entire stack trace. As we have a 
> lot of tasks, when all of the tasks across multiple stages go bad, these 
> error messages accounted for 0.5GB of heap at some point.
> Please correct me if I'm wrong, but it looks like all the task info for 
> running applications are kept in memory, which means it's almost always bound 
> to OOM for long-running applications. Would it make sense to fix this, for 
> example, by spilling some UI states to disk?
