Chen He commented on MAPREDUCE-5002:
------------------------------------
Is this JIRA fixed? If so, could we close it?
> AM could potentially allocate a reduce container to a map attempt
> -----------------------------------------------------------------
>
> Key: MAPREDUCE-5002
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5002
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mr-am
> Affects Versions: 2.0.3-alpha, 0.23.7
> Reporter: Jason Lowe
>
> As discussed in MAPREDUCE-4982, after MAPREDUCE-4893 it is theoretically
> possible for the AM to accidentally assign a reducer container to a map
> attempt if the AM doesn't find a reduce attempt actively looking for the
> container (e.g.: the RM accidentally allocated too many reducer containers).
