First instinct is that you have a name resolution issue. Best Bet: set up forward/reverse DNS. more difficult: hosts file on every machine should map to every other machine.
Setting up bind on your master will take almost no resources, and isn't too difficult. I've never checked with the list if that is recommended or not, if not then list, yell at me now. I have a tutorial on my website on how to set up an authoritative dns server running on ubuntu. http://www.travishegner.com/2009/06/authoritative-dns.html Whether it's causing your issue or not is disputable, but I think most people will agree that having a proper name/address resolution system in place for hadoop/hbase is essential.

Importance: High Ok, I didn't set this cloud up, one of my admins did based on the work I did for the other clouds. When we start up hbase, it looks ok. When I enter hbase shell, I get the shell prompt and when I enter status, I get that all region servers are up. When I type in list, I get a "10/06/01 13:09:56 INFO ipc.HbaseRPC: Server at /10.8.239.185:60020 could not be reached after 1 tries, giving up." Ok... when I try tools zk_dump I get the following: Region servers: - 127.0.0.1:60020 - 10.8.239.89:60020 - 127.0.0.1:60020 - 10.8.239.87:60020 - 10.8.239.95:60020 - 127.0.0.1:60020 - 10.8.239.93:60020 - 10.8.239.91:60020 - 127.0.0.1:60020 - 127.0.0.1:60020 - 127.0.0.1:60020 This doesn't make sense. Why would some of my region servers show up saying that they are local hosts? All of the servers have the same set of configuration files. Thoughts?
