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

             Summary: Improve FileSystem usage in OrcRawRecordMerger
                 Key: HIVE-24655
                 URL: https://issues.apache.org/jira/browse/HIVE-24655
             Project: Hive
          Issue Type: Improvement
            Reporter: Peter Varga
            Assignee: Peter Varga


Some minor performance improvements:
 * Remove exists calls and catch the FileNotFound exception since the exists call just does the same
 * Remove unnecessary delta parsing and file listing when processing deltas
