[jira] [Commented] (HIVE-11976) Extend CBO rules to being able to apply rules only once on a given operator

    [ https://issues.apache.org/jira/browse/HIVE-11976?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14935574#comment-14935574 ] 

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

Patch looks good. May be we should address the following:

1. HivePreFilter Rule the bail out condition should be modified (Pullup predicate should use the child real node).

2. Should we register child filter as well so that rule doesn't fire on child.
