Subject [jira] [Commented] (HIVE-4350) support AS keyword for table alias
Date Tue, 23 Apr 2013 23:49:18 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13639850#comment-13639850

Thejas M Nair commented on HIVE-4350:
-------------------------------------

As this is an optional keyword that does not change the plan, I think it will be safe to modify
an existing test case to use this keyword, instead of adding a new one. That we can avoid
adding couple of seconds to the test runtime.
