Subject [jira] [Commented] (HIVE-11976) Extend CBO rules to being able to apply rules only once on a given operator
Date Mon, 05 Oct 2015 21:03:27 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11976?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14944036#comment-14944036
] 

Laljo John Pullokkaran commented on HIVE-11976:
-----------------------------------------------

[~jcamachorodriguez] Could we add a unit test to make sure that HivePreFilter doesn't get
executed more than once (onMatch) and doesn't get fired on child?

Otherwise looks good.
