Josh Wills updated CRUNCH-181:
------------------------------
Attachment: CRUNCH-181.patch
Yeah, exactly. It occurred to me that we could do a version that uses
ByteBuffers, which will have less overhead than Pairs-- what do you think?
> UUID PType support for Writables

> UUID is a pretty basic and common datatype used for identifiers. It'd be
> nice if there was support through Writables.uuids() similar to other common
> data types.
> The lack of support is most likely due to the lack of formal UUIDWritable
> support in Hadoop itself but a UUIDWritable implementation has been posted
> for awhile[1] and seems pretty trivial to even roll your own and incorporate.
