Subject Re: Cloudera Agent not starting
Date Fri, 13 Mar 2015 17:43:25 GMT
You are getting this error either because the agent cannot bind to the 
address assigned to the hostname nn1.amazonaws.com or the port 9000 is 
already in use.

Check that nn1.amazonaws.com points to an IP address that is actually 
bound to the server.

And check that no other processes are listening on port 9000
