Paul Yang updated HIVE-1056:
----------------------------
Attachment: HIVE-1056.1.patch
* Enables UDTF's to emit rows on close. Although this was disabled initially,
it should be allowed. Without this, the test with lateral views on partitioned
tables will fail.
* Enables PPD for LV. To make pruning easier, a new operator
(LateralViewForward) is placed at the head of every LV DAG. Otherwise, it is
difficult for the pruner to handle the special case for LV's.
