Subject [jira] [Commented] (HIVE-4042) ignore mapjoin hint
Date Wed, 20 Feb 2013 05:09:13 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4042?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13581953#comment-13581953

Namit Jain commented on HIVE-4042:
----------------------------------

Mapjoin hint is only needed for bucketed/sorted tables.
It might be a good idea to just ignore the hint, if the underlying table is not bucketed/sorted.
