             Summary: Missing break in ZooKeeperLeaderRetrievalService#handleStateChange()
                 Key: FLINK-3809
                 URL: https://issues.apache.org/jira/browse/FLINK-3809
             Project: Flink
          Issue Type: Bug
            Reporter: Ted Yu


{code}
  protected void handleStateChange(ConnectionState newState) {
    switch (newState) {
      case CONNECTED:
        LOG.debug("Connected to ZooKeeper quorum. Leader retrieval can start.");
      case SUSPENDED:
        LOG.warn("Connection to ZooKeeper suspended. Can no longer retrieve the leader from " +
          "ZooKeeper.");
      case RECONNECTED:
        LOG.info("Connection to ZooKeeper was reconnected. Leader retrieval can be restarted.");
      case LOST:
        LOG.warn("Connection to ZooKeeper lost. Can no longer retrieve the leader from " +
          "ZooKeeper.");
    }
{code}
Except for LOST state, the other states would lead to multiple logs.
