Owen O'Malley updated HADOOP-5528:
----------------------------------
Status: Open (was: Patch Available)
I think this would be much clearer if the attribute names were:
mapred.binary.partitioner.offset
mapred.binary.partitioner.length
especially if you used max(key.length, mapred.binary.partitioner.length) so
that you could set it to a large value and use the entire key.

> It would be useful to have a {{BinaryPartitioner}} that partitions
> {{BinaryComparable}} keys by hashing a configurable part of the bytes array
> corresponding to each key.
