Subject New supervisor is not able to join cluster (storm 1.0.2)
Date Fri, 23 Mar 2018 10:39:21 GMT

I have storm cluster that basically works fine. Now I have to add two 
more supervisors to this cluster and when I'm doing that I get this 
exception (on supervisor machine that is being added):

2018-03-23 10:17:45.539 o.a.s.d.supervisor [INFO] Downloading code for 
storm id topo1


2018-03-23 10:17:55.629 o.a.s.d.supervisor [WARN] There was a connection 
problem with nimbus. #error {
  :cause Connection refused (Connection refused)

The only difference between already working supervisors and new 
supervisor is that the new one is in different network.


- new supervisor machine is listed in UI;

- I can telnet nimbus machine from new supervisor machine on port 6627;

- tcpdump used on new supervisor machine tells me that new supervisor 
machine is using 6627 port only (there is no other communication with 

- nimbus machine correctly responds with checkStatus (it is logged in 
nimbus log and I can see this in tcpdump).

And now I don't know what to try now.

Is there any nimbus option that forbids communication like this? Maybe 
sth like this is on the supervisor side?

What can I do more to find out what is wrong in here?
