[jira] [Created] (HIVE-14516) OrcInputFormat.SplitGenerator.callInternal() can be optimized

Eugene Koifman created HIVE-14516:
-------------------------------------

             Summary: OrcInputFormat.SplitGenerator.callInternal() can be optimized
                 Key: HIVE-14516
                 URL: https://issues.apache.org/jira/browse/HIVE-14516
             Project: Hive
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 2.2.0
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman


callIntenal() has 
        // We can't eliminate stripes if there are deltas because the
        // deltas may change the rows making them match the predicate.

but in Acid 2.0, the deltas only have delete events thus eliminating stripes from  "base" of split should be safe.
