It's a minor thing, but correct naming of the patch (for example) helps
committers when processing the queues. Thanks!

> 1. Configure the zookeeper to start in cluster mode like below-
> clientPort=2181
> server.1=10.18.101.80:2888:3888
> server.2=10.18.219.50:2888:3888
> server.3=10.18.221.194:2888:3888
> and not like below:-
> server.1=10.18.101.80:2888:3888:participant;2181
> server.2=10.18.219.50:2888:3888:participant;2181
> server.3=10.18.221.194:2888:3888:participant;2181
> 2. Start the cluster and one client using >zkCli.sh
> 3. execute command "config -c"
> It is throwing nullpointerException:-
