[jira] Commented: (HIVE-1858) Implement DROP {PARTITION, INDEX, TEMPORARY FUNCTION} IF EXISTS

["John Sichi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-1858?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12975308#action_12975308 ] 

John Sichi commented on HIVE-1858:
----------------------------------

+1.  Will commit if tests pass.

The wiki is going to need to be updated for this plus HIVE-1856.  Be sure to include a note that the new syntax + conf is only available starting from Hive 0.7.
