[jira] [Commented] (HIVE-1662) Add file pruning into Hive.

    [ https://issues.apache.org/jira/browse/HIVE-1662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13595482#comment-13595482 ] 

Joydeep Sen Sarma commented on HIVE-1662:
-----------------------------------------
