Alan Gates updated PIG-334:
---------------------------

    Status: Patch Available  (was: Open)

I'll file a separate bug for sorting on types other than byte array.

> In the new pipeline, when possible, pig uses hadoop writable comparable types for the
hadoop key rather than tuple.  As of hadoop 0.17 there is no DoubleWritable type.  It has
been added for hadoop 0.18.  But it appears that we will be ready to integrate the types branch
back into trunk before hadoop 0.18 is released.  So we need to implement a DoubleWritable
for ourselves until that time.
> The code can be taken from HADOOP-3061.  The code where we convert to and from hadoop
types (DataType.getWritableComparableTypes and convertToPigType) needs to be changed to use
this type.
