Description

byte[] currentId = ZKUtil.getDataAndWatch(watcher, leaderZNode);
if (currentId != null && Bytes.equals(currentId, nodeId)) {
  ....
} else {
  LOG.info("Found existing leader with ID: {}", Bytes.toStringBinary(nodeId));
  leaderExists.set(true);
}

Existing id, read from ZK, is currentId. But by mistake we log 'nodeId' which is the this master's node id.
