[jira] [Created] (ORC-498) ReaderImpl and RecordReaderImpl open separate file handles

Owen O'Malley created ORC-498:
---------------------------------

             Summary: ReaderImpl and RecordReaderImpl open separate file handles
                 Key: ORC-498
                 URL: https://issues.apache.org/jira/browse/ORC-498
             Project: ORC
          Issue Type: Bug
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley


The older versions of ORC used the same file handle to read the file footer and the data. The current code opens a file handle to read the footer and a separate file handle to read data, which doubles the number of opens on the Name Node.
