Even if the passed nodeId argument is wrong an NPE is not acceptable. I will
raise an issue.

Yes,
if you want to "control" the cluster member, you can use multicast,
static definition, or cloud whiteboard.

Yes, by default, Cellar uses Unicast for discovery (you can switch to
another mechanism).
It means that, you simply install Cellar on any Karaf instance, and it
will join automatically the cluster.

Hi Jean. It worked.

You have to use the correct node ID.
If you try something like:
karaf@root> cluster:ping d-177889.wipro.com:5701
it should work.

karaf@root> cluster:list-nodes
No. Host Name Port ID
* 1 D-183913.wipro.com 5701 D-183913.wipro.com:5701
2 d-177889.wipro.com 5701 d-177889.wipro.com:5701

Why its not pinging then? Is it anything related to proxy ?

Could you check the node name using cluster:list-nodes ?
