Till Rohrmann commented on FLINK-6522: -------------------------------------- Hi [~zjureel], yes clean up will entail removing all Zk data written under the root path. Additionally we have to cleanup the data written to the {{SubmittedJobGraphStore}}. For that, we probably have to keep a reference to the {{RetrievableStateStorageHelper}} used by the created {{ZooKeeperSubmittedJobGraphStore}}. This might entail some refactorings for the {{ZooKeeperUtils}} methods. > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
