------------------------------------

Tsuyoshi,

I've resolved MAPREDUCE-4253 for you (thanks!), and hopefully this can now proceed if it was blocked due to that.

> KeyFieldBasedComparator and KeyFieldBasedPartitioner are libraries so should not appear as getters and setters in JobConf. For the new API there are getters and setters on KeyFieldBasedComparator and KeyFieldBasedPartitioner themselves - we should add the equivalent to the old API and deprecate the references in JobConf.
