> 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, 2.7.0
> Reporter: Jason Lowe
> Assignee: Chang Li
> Attachments: MAPREDUCE-5002.1.patch, MAPREDUCE-5002.2.patch,
> MAPREDUCE-5002.2.patch
>
>
> 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).
