Hi,
I have created a 6 machine Hadoop cluster using Centos 6.5 VMs that run under one Affinity group. They have a single DNS called zmclient.cloudapp.net. I have used powershell to force static IPs with in the subnet I had created.
The problem is that when I try and launch Hadoop, it errors staying port 9000 is inaccessible. Firewall are shut down on all VMs. Using Linux commands, I have checked the available ports but I cannot find port 9000 in the list. I also tried to enable port 9000 but to no avail. I also created endpoints on this ports, choosing TCP and 9000 for internal and random number external.
I want these ports to be open internally:
9000 to 9039
50070 to 60070
8000 to 9000
Error is:
