I've just built my distributed cluster but am getting the following error
when I try to use HDFS.
I've traced it by telnet to 192.168.1.12 50010 and it just waits there
waiting for a connection but never happens.
If I telnet on that host using localhost (127.0.0.1) the telnet connection
happens immediately.
What could be the cause?
