>
> because in enqueueSuccessfulTask there is another thread to fetch result, if
> result is very large,it maybe throw a OutOfMemoryError. so if we donot catch
> OutOfMemoryError, DAGDAGScheduler donot know the status of this task.
> another is:
> when totalResultSize > maxResultSize and it cannot fetch large result, we
> need to report failed status to DAGDAGScheduler. if it donot report any
> status of this tasks.DAGDAGScheduler also donot know status of this task.
