      Description

      The default pickler compressor switched from zlib to bz2 in https://github.com/apache/beam/commit/103facbf80c2e4786e60367161ec59352196d04a#diff-c0972fb2e432f61d6dd354ca320853c520d0b414bb0113e375e1b077c8ec785c, this will change the pickled Coder representations in the job graph and lead to pipeline update failure on Dataflow.

      Sdk versions using bz2 in Coder pickler may not be update-able to future sdk versions on dataflow.
