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:-
