This was a bug at HBase 1.0.1, it has been patched, so an update to 1.0.2 or further should solve the problem. URL for the Jira thread: https://goo.gl/c5oa6f

  • Unable to connect to certain 1.7.2 servers, at any time. This doesn't affect all servers, and seems to be this connection specifically, as I've tried it on a Mac (Mac OSX Snow Leopard, Java 32-bit Update 7 version 45) and it gave me a similar error, io.netty.ConnectException: Connection timed out: no further exceptions. I know that the server works, as I am actively talking with people who are using the server, trying to help me get on. This is the output in the Development console when the connection fails.
