I'll file a separate bug for sorting on types other than byte array.
> Sorting on fields of type double does not work
> ----------------------------------------------
>
> Key: PIG-334
> URL: https://issues.apache.org/jira/browse/PIG-334
> Project: Pig
> Issue Type: Bug
> Components: impl
> Affects Versions: types_branch
> Reporter: Alan Gates
> Assignee: Alan Gates
> Priority: Critical
> Fix For: types_branch
>
> Attachments: doublesort.patch
>
>
> 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.
