>
> 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.
