Hi.

I have a cluster of storm with 3 servers:

Server 1: zookeeper, nimbus and one supervisor

Server 2: one supervisor

Server 3: one supervisor

When I start the supervisors on the server 2 and server 3, the Server 1 identify OK the supervisors and I can see on the UI 3 supervisors, but when I deploy a topology and rebalance it, on the logs of supervisors of Server 2 and Server 3  show the next exception:

I need open a special port? or specials permissions??
