[jira] [Created] (HIVE-5091) ORC files should have an option to pad stripes to the HDFS block boundaries

Owen O'Malley created HIVE-5091:
-----------------------------------

             Summary: ORC files should have an option to pad stripes to the HDFS block boundaries
                 Key: HIVE-5091
                 URL: https://issues.apache.org/jira/browse/HIVE-5091
             Project: Hive
          Issue Type: Bug
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley


With ORC stripes being large, if a stripe straddles an HDFS block, the locality of read is suboptimal. It would be good to add padding to ensure that stripes don't straddle HDFS blocks.
