Hi,
We have a resource manager with 4 node managers. Upon submitting the mapreduce job to the resource manager, it is getting stuck while at getResources() for 10 min, timing out and then it is trying other node manager. When only one nodemanager running, everything is fine. Upon turning off the firewall on all node managers, everything seems working. Upon looking at the netstat, it was wide range of ports between 30000 to 61000 that noedmanagers/reosurcemanagers were communicating. So I opened the tcp ports in the range 30000:61000 and turned on the firewall. But it does not seem to work. Any idea, what needs to be done here? Thx -Hitarth
