Alan Gates commented on PIG-305:
--------------------------------
At least part of the issue is the logical plan in the above query is not
correctly connected together. This looks related to what Tyson reported in
PIG-299. Don't know whether it's a duplicate or if there are additional
issues. Assigning to Santhosh to at least deal with the parser issues.
> Nested order by queries return only one key instead of all keys
