      Description

      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.
