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

             Summary: Breaking HighAvailabilityServices interface by adding new method
                 Key: FLINK-22721
                 URL: https://issues.apache.org/jira/browse/FLINK-22721
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.14.0, 1.13.1, 1.12.5
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.14.0, 1.13.1, 1.12.5


As part of FLINK-20695 we introduced a new method to the {{HighAvailabilityServices.cleanupJobData}} interface. Since this method has not default implementation it is currently breaking change. Since Flink allows to implement custom Ha services using this interface, I suggest adding a default implementation for this method.
