[jira] [Updated] (BEAM-11113) Default compressor change breaks dataflow python streaming job update compatibility

     [ https://issues.apache.org/jira/browse/BEAM-11113?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Yichi Zhang updated BEAM-11113:
-------------------------------
    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.
