[jira] [Commented] (CALCITE-1365) Introduce UnionPullUpConstantsRule

    [ https://issues.apache.org/jira/browse/CALCITE-1365?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15457654#comment-15457654 ] 

Jesus Camacho Rodriguez commented on CALCITE-1365:
--------------------------------------------------

There was a wrong method call in the md provider : it should have been _isAlwaysTrue_, which is the case when we do not need to add the pred to the inferred list (it is that way in Hive, I think it ended up changed when I copied/pasted the code).

Fix up in : http://git-wip-us.apache.org/repos/asf/calcite/commit/317802d
