> I have started the ZK cluster and when tries to create a BookKeeper client
> from my application, it is throwing following ZooKeeper
> ConnectionLossException and is exitting.
> 12/06/01 11:44:31 WARN client.ZooKeeperSaslClient: SecurityException:
> java.lang.SecurityException: Unable to locate a login configuration occurred
> when trying to find JAAS configuration.
> 12/06/01 11:44:31 INFO client.ZooKeeperSaslClient: Client will not
> SASL-authenticate because the default JAAS configuration section 'Client'
> could not be found. If you are not using SASL, you may ignore this. On the
> other hand, if you expected SASL to work, please fix your JAAS configuration.

> 12/06/01 11:44:36 WARN client.ZooKeeperSaslClient: SecurityException:
> java.lang.SecurityException: Unable to locate a login configuration occurred
> when trying to find JAAS configuration.
> When analyzed more, the root cause is:
> BookKeeper.java:
> --------------------
> In the constructor of BookKeeper, immediately after creating the ZK client ,
> it is going to bookieWatcher.readBookiesBlocking() for available bookies from
> ZK server before reaching SyncConnected event.
> I think, we would properly use the existing countdown latch and wait till
> ZooKeeper client connection establishment before continue reading Bookies.
