Description

Hive has its own implementations of ByteWritable/DoubleWritable/ShortWritable. We cannot replace usage of these classes since they will break 3rd party UDFs/SerDes, however we can at least extend from the Hadoop version of these classes when possible to avoid duplicate code.

When Hive finally moves to version 1.0 we might want to consider removing use of these Hive-specific writables and switching over to using the Hadoop version of these classes.

ShortWritable didn't exist in Hadoop until 2.x so it looks like we can't do it with this class until 0.20/1.x support is dropped from Hive.
