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

             Summary: Add ZooKeeper cleanup logic to ZooKeeperHaServices
                 Key: FLINK-6522
                 URL: https://issues.apache.org/jira/browse/FLINK-6522
             Project: Flink
          Issue Type: Improvement
          Components: Distributed Coordination
    Affects Versions: 1.3.0, 1.4.0
            Reporter: Till Rohrmann


The {{ZooKeeperHaServices}} provide a {{CuratorFramework}} client to access ZooKeeper data. Consequently, all data (also for different job) are stored under the same root node. When {{HighAvailabilityServices#closeAndCleanupAllData}} is called, then this data should be cleaned up. This cleanup logic is currently missing.
