Alan Gates updated PIG-292:
---------------------------
Attachment: manysortfixes.patch
This patch contains a lot. The relevant areas are:
1) Fixed DataByteArray.compareTo to first check byte to byte and only size when
the bytes compare equal, instead of other way around (that is, it now matches
String.compareTo behavior).
2) Fixed use of binary comparator for hadoop sorting. It was being used anytime
we were sorting on a tuple. It should instead be used anytime we are not doing
an order by.
> Order by on more than one field returns wrong order

> Pig scripts with order by of a single column work fine. But once a second
> column is added the data is returned in the wrong order.
