Brad Tofel commented on PIG-282:
--------------------------------
Do I read this right - there is no way to specify a custom partitioner for use
with "ORDER BY"?
If so, is there any other way to perform a total ordering within Pig?
I will be doing a STORE immediately after the ORDER - the relation will not be
used again. Is there some other work around to achieve this?
I would love to replace my current Hadoop Java code with Pig, but total
ordering is a requirement.

> By adding custom partitioner we can give control over which output partition
> a key (/value) goes to. We can add keywords to language e.g.
> PARTITION BY UDF(...)
> or a similar syntax. UDF returns a number between 0 and n-1 where n is number
> of output partitions.
