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.");

Except for LOST state, the other states would lead to multiple logs.
