Hi Subbarao,

Which AMI are you using? This error usually occurs because you're
using an AMI that does not allow root logins.

In general you should use either the StarCluster supported AMIs or an
AMI based on the StarCluster supported AMIs. Have a look at the
following doc on how to customize the StarCluster supported AMIs:

http://web.mit.edu/star/cluster/docs/latest/manual/create_new_ami.html

Also, do you still have the 'crash report' that was generated when you
got this error? It would be useful to take a look at this as well if
it's still around....
