Unable to access AWS EC2 server


I am not able to access hadoop from the server "ubuntu@ec2-54-69-192-192.us-west-2.compute.amazonaws.com". I can login to the server using putty, but when I try to access the hadoop file system i.e. by issuing the command "hdoop fs -ls" I am getting the error "connection refused". It's same for all of these "hadoop fs -ls /, hadoop dfs -ls /". I have sent an email to hadoop@dezyre.com for support, but no reply from them.

Please find the attached error log for more information and suggest.
