> KeyFieldBasedPartitioner not partitioning properly when configured

> Key: MAPREDUCE-4771
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4771
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.3, 2.0.1-alpha
> Reporter: Jason Lowe
> Assignee: Jason Lowe
> Attachments: MAPREDUCE-4771.patch
>
>
> Relative to Hadoop 0.20/1.x, KeyFieldBasedPartitioner is not distributing
> across partitions properly when configured. This is related to the
> double-configure issue as described in HADOOP-7425. KeyFieldBasedPartitioner
> is getting configured twice, and that ends up duplicating the keyspecs and
> causing the keys to be hashed twice.
> KeyFieldBasedPartitioner should not duplicate keyspecs when configured twice.
