Subject [jira] [Updated] (HIVE-4242) Predicate push down should also be provided to InputFormats

Phabricator updated HIVE-4242:
------------------------------

    Attachment: HIVE-4242.D9831.1.patch

omalley requested code review of "HIVE-4242 [jira] Predicate push down should also be provided
to InputFormats".

Reviewers: JIRA

HIVE-4242 predicate pushdown for all input formats

Currently, the push down predicate is only provided to native tables if the hive.optimize.index.filter
configuration variable is set. There is no reason to prevent InputFormats from getting the
required information to do predicate push down.

Obviously, this will be very useful for ORC.
