Subject [jira] [Commented] (HIVE-5047) Hive client filters partitions incorrectly via pushdown in certain cases involving "or"
Date Tue, 13 Aug 2013 01:40:48 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5047?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13737698#comment-13737698
] 

Sergey Shelukhin commented on HIVE-5047:
----------------------------------------

What do you mean? It can be an arbitrarily complex combo. Right now it's bottom up so children
become null if they cannot be sent, and "eliminate" the parents, so we don't know the result
before we call it in children.
Also if both sides of "or" are available then it is valid to sent it up.
