[jira] [Created] (HIVE-12843) One path for ORC ACID reading (Vectorized) when file is original and there are no deltas appears to not do Schema Evolution

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

             Summary: One path for ORC ACID reading (Vectorized) when file is original and there are no deltas appears to not do Schema Evolution
                 Key: HIVE-12843
                 URL: https://issues.apache.org/jira/browse/HIVE-12843
             Project: Hive
          Issue Type: Bug
          Components: Hive
            Reporter: Matt McCline
            Priority: Critical


>From code reading, it appears that VectorizedOrcInputFormat.getRecordReader fetches the file meta data when an OrcSplit is used ...  It can come down this path for ACID when the split is original and there are no deltas.  Is this ok?
