> Attempt(map or reduce) remains NEW(state). And job is stuck in certain
> conditions.
> The following are the situations:
> # total task(map/reduce) count is same as the running limit of
> task(mapreduce.job.running.map.limit/mapreduce.job.running.reduce.limit).
> # And start job. -> And total tasks(map/reduce) are running. -> And failed
> attempt for some reasons.
> # Request allocation of new containers because the attempt failed.
> # Quickly receive allocation of new containers.
> # However, new container is released because failed attempts have not been
> cleared up.(allocated == total == running limit)
> # Subsequently, the failed attempts is terminated, but it is waiting forever.
> # Job is stuck.
> We switched MR frameworks(2.7.1) and checked that it worked well.
> Perhaps it is related to -MAPREDUCE-6697-
> Can you help me?
