Chris Douglas updated HADOOP-4151:
----------------------------------

    Attachment: 4151-4.patch

BinaryComparable is probably clearer. Sorry about the bin/hadoop change; that belongs with
HADOOP-3019 (which is missing it *oops*). Updated patch

> Sometimes it's beneficial to treat types (like BytesWritable and Text) as byte arrays,
agnostic to their type. Adding an interface to tag key types as amenable to this treatment
can permit optimizations and reuse for that subset of types in tools and libraries.
