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

             Summary: Add per job cleanup methods to HighAvailabilityServices
                 Key: FLINK-6521
                 URL: https://issues.apache.org/jira/browse/FLINK-6521
             Project: Flink
          Issue Type: Improvement
          Components: Distributed Coordination
    Affects Versions: 1.3.0, 1.4.0
            Reporter: Till Rohrmann


The {{HighAvailabilityServices}} are used to manage services and persistent state at a single
point. This also entails the cleanup of data used for HA. So far the {{HighAvailabilityServices}}
can only clean up the data for all stored jobs. In order to support cluster sessions, we have
to extend this functionality to selectively delete data for single jobs. This is necessary
to keep data for failed jobs and delete data for successfully executed jobs.
