[jira] [Created] (HIVE-5102) ORC getSplits should create splits based the stripes

Owen O'Malley created HIVE-5102:
-----------------------------------

             Summary: ORC getSplits should create splits based the stripes 
                 Key: HIVE-5102
                 URL: https://issues.apache.org/jira/browse/HIVE-5102
             Project: Hive
          Issue Type: Bug
          Components: File Formats
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley


Currently ORC inherits getSplits from FileFormat, which basically makes a split per an HDFS block. This can create too little parallelism and would be better done by having getSplits look at the file footer and create splits based on the stripes.
