Subject [jira] Commented: (HIVE-1660) Change get_partitions_ps to pass partition filter to database
Date Fri, 31 Dec 2010 23:57:46 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1660?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12976369#action_12976369

John Sichi commented on HIVE-1660:
----------------------------------

Namit, HIVE-1660.4.patch contains no reference to hbase_pushdown.q.out.  However, your commit
did change that file:

http://svn.apache.org/viewvc?view=revision&revision=1024341

I am guessing that the commit for HIVE-1638 (close in time) broke this test, and then you
updated the log file as part of this commit.

> Support for doing partition pruning by passing the partition filter to the database is
added by HIVE-1609. Changing get_partitions_ps to use this could result in performance improvement
 for tables having large number of partitions. A listPartitionNamesByFilter API might be required
for implementing this for use from Hive.
