    Description

      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.
