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

             Summary: Closing lots of RecordWriters is slow
                 Key: HIVE-4250
                 URL: https://issues.apache.org/jira/browse/HIVE-4250
             Project: Hive
          Issue Type: New Feature
          Components: Serializers/Deserializers
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley


In FileSinkOperator, all of the RecordWriters are closed sequentially. For 
queries with a lot of dynamic partitions this can add substantially to the task 
time. For one query in particular, after processing all of the records in a few 
minutes the reduces spend 15 minutes closing all of the RC files.
