Rohini Palaniswamy updated PIG-3565:
------------------------------------
Attachment: PIG-3565-2.patch
Fixed orderby and addressed review comments. Reverted the accidental change in
Union as I had taken the initial uploaded patch and started the rebasing work.
Did not notice that later. Thanks for catching that.
Additional TODO:
- Split followed by join (multiple level of splits) and orderby needs to be
fixed.
Additional things to fix (need new jiras):
- With change to calculating splits on the client instead of AM, order by
following split,groupby, etc is broken because the temporary files are not
present when DAG is built.
- Found that order by desc is not working and is always ordered in ascending
order.
- The Join_1 failure is because the join is not deterministic and left and
right side get interchanged. If you rerun again it, it will pass. This needs to
be fixed.
- Also found that with the POPackage changes, MR MultiQuery is broken.
