[jira] [Closed] (SPARK-5583) Support unique join in hive context

["Reynold Xin (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SPARK-5583?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Reynold Xin closed SPARK-5583.
------------------------------
    Resolution: Won't Fix

Going to close this one as won't fix since it is a weird syntax that only Hive has (and as far as I know not that many Hive users know about it).

The patch is already on GitHub. We can merge that in the future if there is strong demand.
