Hi, Three region servers are online and I confirmed it here http:// <master_hostname>:60010/master-status
This page also lists all my tables. When I click on tables where I had errors, it is not showing any details and browser hangs. I think this means region server details are not correctly stored for those tables. I have reverse DNS issue in one of my region server. When I enter "hostname <ip>", in one of my region server, I get following error Host 131.32.78.10.in-addr.arpa. not found: 3(NXDOMAIN) But I was able to create table and load data two hours back. Also I checked region server status of this specific machine http://<region server with reverse DNS issue>:60030/rs-status and the result is positive. So I have doubts in role of reverse DNS in this problem.
