  • Enum Constant Details

    • Unknown

      @Deprecated public static final Watcher.Event.KeeperState Unknown
      Deprecated.
      Unused, this state is never generated by the server
    • Disconnected

      public static final Watcher.Event.KeeperState Disconnected
      The client is in the disconnected state - it is not connected to any server in the ensemble.
    • NoSyncConnected

      @Deprecated public static final Watcher.Event.KeeperState NoSyncConnected
      Deprecated.
      Unused, this state is never generated by the server
    • SyncConnected

      public static final Watcher.Event.KeeperState SyncConnected
      The client is in the connected state - it is connected to a server in the ensemble (one of the servers specified in the host connection parameter during ZooKeeper client creation).
    • AuthFailed

      public static final Watcher.Event.KeeperState AuthFailed
      Auth failed state
    • ConnectedReadOnly

      public static final Watcher.Event.KeeperState ConnectedReadOnly
      The client is connected to a read-only server, that is the server which is not currently connected to the majority. The only operations allowed after receiving this state is read operations. This state is generated for read-only clients only since read/write clients aren't allowed to connect to r/o servers.
    • SaslAuthenticated

      public static final Watcher.Event.KeeperState SaslAuthenticated
      SaslAuthenticated: used to notify clients that they are SASL-authenticated, so that they can perform Zookeeper actions with their SASL-authorized permissions.
    • Expired

      public static final Watcher.Event.KeeperState Expired
      The serving cluster has expired this session. The ZooKeeper client connection (the session) is no longer valid. You must create a new client connection (instantiate a new ZooKeeper instance) if you with to access the ensemble.
    • Closed

      public static final Watcher.Event.KeeperState Closed
      The client has been closed. This state is never generated by the server, but is generated locally when a client calls ZooKeeper.close() or ZooKeeper.close(int)
