> LocalBookKeeper is initializing the zkclient and immediately trying to create "/ledgers" and "/ledgers/available" znodes without waiting for the ZooKeeper SyncConnected state. The client operation should be guarded with ZKConnectionWatcher.
> LocalBookKeeper.java
> {noformat}
> zkc = new ZooKeeper("127.0.0.1", ZooKeeperDefaultPort, new emptyWatcher());
> /* User for testing purposes, void */
