> Key: MAPREDUCE-6697
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6697
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 2.7.0
> Reporter: Jason Lowe
> Assignee: Nathan Roberts
>
> The concurrent task limit feature should only adjust the ANY portion of the
> AM heartbeat ask when a limit is truly necessary, otherwise extraneous
> containers could be allocated by the RM to the AM adding some overhead to
> both. Specifying a concurrent task limit that is beyond the total number of
> tasks in the job should be the same as asking for no limit.
