[jira] [Commented] (HIVE-4904) A little more CP crossing RS boundaries

    [ https://issues.apache.org/jira/browse/HIVE-4904?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13747256#comment-13747256 ] 

Navis commented on HIVE-4904:
-----------------------------

[~yhuai] Sorry. I've missed your message. 
RS is CPed only when the child of it is JOIN operator and SELECT skips CP if any of children is FS/UNION/UDTF, etc.

> Currently, CP context cannot be propagated over RS except for JOIN/EXT. A little more CP is possible.
