Subject [jira] [Comment Edited] (HIVE-14214) ORC Schema Evolution and Predicate Push Down do not work together (no rows returned)

    [ https://issues.apache.org/jira/browse/HIVE-14214?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15375539#comment-15375539

------------------------------------------------------------------

HBase metadata PPD feature is not complete right now (or rather it should work and is somewhat
usable but it's alpha with HBase metastore and there's convenience and testing to be added).
Unless I am missing something it should be ok to break it as long as it breaks in a reasonable
manner (e.g. throws suggesting the user not enable it, it's off by default), and there's a
followup JIRA

to evaluate predicate push down.
