-------------------------------------
Summary: 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: 2.0.1-alpha, 0.23.3
Reporter: Jason Lowe
Assignee: Jason Lowe
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.
