Chris Douglas commented on HADOOP-5528:
---------------------------------------
* It would make sense for the deprecated partitioner class to extend the
partitioner from mapreduce, per the idiom used in HADOOP-1230
* Code using BinaryPartitioner might be more readable if it had a static method
for setting the left and right indices in the config. There are other examples
in lib
* The indexer class hierarchy confuses me. Instead of making the semantics
configurable, defining and describing them in the aforementioned static method
would be much easier. I'd also be a fan of using the python semantics, all the
time.

> corresponding to each key.
