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

             Summary: End-to-end test: Job upgrade
                 Key: FLINK-8978
                 URL: https://issues.apache.org/jira/browse/FLINK-8978
             Project: Flink
          Issue Type: Sub-task
          Components: Tests
    Affects Versions: 1.5.0
            Reporter: Till Rohrmann
             Fix For: 1.5.0


Job upgrades usually happen during the lifetime of a real world Flink job. Therefore, we should add an end-to-end test which exactly covers this scenario. I suggest to do the follwoing:
# run the general purpose testing job FLINK-8971
# take a savepoint
# Modify the job by introducing a new operator and changing the order of others
# Resume the modified job from the savepoint
# Verify that everything went correctly
