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.

[jira] Commented: (PIG-301) ORDER BY DESC doesn't work at all

Pi Song commented on PIG-301:
-----------------------------
The current implementation also doesn't seem to handle different order directions.
{noformat}
B = ORDER A BY $0 DESC, $1 ASC, $2 DESC, $3 ASC
{noformat}
I think implementation-wise, we should somehow implement PigWriteableComparator using composite design pattern.
