Finally, seems that this is not blocking the application. It's stated as "ERROR"s but it's still running after that. After some time, I'm getting some results. I don't have any DNS on my cluster. All servers have the same host file and static IPs. Is it mandatory to have a DNS to run HBase? Or can it run without?
