Storm supervisor not registering itself with the zookeeper


1.) When supervisor is in other node than that of the zookeeper,

ConnectionState [ERROR] Connection timed out
org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss

2.) When supervisor is in the same node as of the zookeeper,

supervisor [ERROR] Error on initialization of server mk-supervisor AI: AI



This is because the firewall of the zookeeper system is not allowing it to accept the connections.While we can solve the 2nd scenario by adding the ip address and the hostname to the /etc/hosts file. Both the problems can be fixed by turning the firewall off by following commands,

service iptables save

service iptables stop
