Subject [jira] [Commented] (HIVE-11104) Select operator doesn't propagate constants appearing in expressions
Date Thu, 25 Jun 2015 05:41:04 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11104?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14600725#comment-14600725
] 

Prasanth Jayachandran commented on HIVE-11104:
----------------------------------------------

1) Can the getSignature() call return null? I have seen null checks in other places.
2) Can you add explain of the query as well to the q file?
