Alan Gates updated PIG-301:
---------------------------
Attachment: orderdesc.patch
This patch provides raw comparators for pig types so that we can handle order
by descending. It uses hadoop's RawComparator interface, because these raw
comparators can also implement Configurable. The ascending/descending array is
passed in the JobConf and then deserialized in the setConf call.
Much of the work of this patch was actually done by Santhosh.
> ORDER BY DESC doesn't work at all
