Hi Ranjit,

Did you add the instance to a _at_sc-* group when creating the instance in
the Amazon console? That would cause the warning you're getting. In any
case if you're sure you did not launch with StarCluster you can safely
ignore the warning. The warning will be completely removed in the next
version as this limitation of not being able to use StarCluster-started
instances is gone in the latest development code.

The user id you need to use is the numerical account id.

HTH,

~Justin
