Why don't you email me directly oGLOWo at gmail and I might be able to help you so we don't pollute the dev list. 

I'll be up all night today for the next 10 hours so if you email me, we can get on hangouts, skype, etc

After explicitly enabling port
9160 (Cassandra client port (Thrift)) in that particular node it's connected to ring however other nodes are working with same configuration.

Now Opscenter is installed in that particular node after explicitly enabling
61620 (OpsCenter monitoring port), 61621 (OpsCenter agent port) in all nodes though in other nodes error is displaying while installing from GUI as

"Unable to find a java executable! Please install java or set JAVA_HOME. Exit code: 4".

Though java is installed & JAVA_HOME is also set for all users.
$ echo $JAVA_HOME


Please help!

This may not be recommended, might/should(?) work, and may be a reason [0]. My first suggestion would be to remove this variable. This would also give you a chance to go through the steps of adding a new node to the cluster again [1] - you might stumble on something.
