Ideally it'd be good to do the whole test suite to verify that IAM works across
the lot, however I think we can take the fact that your test suite, which does
use IAM, scaled up, is implicitly a sign that the auth mechanism works

I have tried out this patch in AWS test environment and fixes the issue. Are
you referring to running entire test suite in aws ec2?.

LGTM, +1, pending
# it passing a full test run against your endpoint
# you doing a look at the generated aws site page (or a github/markdown editor)
to make sure the 1. 2 ... bullet points are pulled out. I think you may need an
extra line.
Rajesh or someone running on EC2 will presumably need to check that it works
too —we aren't testing that, are we? (though presumably you could run the
integration tests using IAM to pick up the credentials —has someone done that?)

LGTM
Could you have that 1) 2) 3) list in both the docs and md formatted for each.
that is for the javadocs and 1. 2. for markdown?
