[jira] [Commented] (HIVE-12184) DESCRIBE of fully qualified table fails when db and table name match and non-default database is in use

["Xuefu Zhang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-12184?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14994498#comment-14994498 ] 

Xuefu Zhang commented on HIVE-12184:
------------------------------------

Actually I'm not sure if we need .$...$ part after the column. Since the structure can be nested to artificially any level, going down one layer doesn't help much. Plus, it seems making things complicated.
