Subject [jira] [Commented] (HIVE-5718) Support direct fetch for lateral views, sub queries, etc.
Date Mon, 03 Nov 2014 22:24:37 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5718?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14195228#comment-14195228
] 

Laljo John Pullokkaran commented on HIVE-5718:
----------------------------------------------

Instead of walking the QB tree and parsing the subquery aliases, can't we make use of "ParseContext.topToTable"
to get to the Table object given TS op?
