Subject [jira] [Commented] (HIVE-12184) DESCRIBE of fully qualified table fails when db and table name match and non-default database is in use
Date Fri, 06 Nov 2015 21:52:11 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12184?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14994522#comment-14994522

Naveen Gangam commented on HIVE-12184:
--------------------------------------

It was already supported prior to this change. I dint have to do anything specific with my
change, except had to be mindful that the tree could contain other children for such usage.
There are existing unit tests that tested this behavior clientpositive/describe_xpath.q and
clientnegative/describe{1..4}.q
