Subject [jira] Updated: (HIVE-1056) Predicate push down does not work with UDTF's
Date Thu, 08 Apr 2010 23:24:36 GMT

     [ https://issues.apache.org/jira/browse/HIVE-1056?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
