                 Key: HIVE-4516
                 URL: https://issues.apache.org/jira/browse/HIVE-4516
             Project: Hive
          Issue Type: Bug
            Reporter: Jon Hartlaub


A patch for concurrent use of TimestampWritable which occurs in a multithreaded scenario (as
found in AmpLab Shark).  A static SimpleDateFormat (not ThreadSafe) is used by TimestampWritable
in CTAS DDL statements where it manifests as data corruption when used in a concurrent environment.
