Subject [jira] Commented: (HIVE-1534) Join filters do not work correctly with outer joins
Date Wed, 08 Sep 2010 05:24:33 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1534?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12907094#action_12907094

Amareshwari Sriramadasu commented on HIVE-1534:
-----------------------------------------------

bq. I would suggest not supporting filters in the join condition for outer joins, since we
are returning wrong results.
Created HIVE-1621 for this. Leaving this jira to do the correct fix.
