I tried editing user Trust relationship of Default Role but again it says not authorized.ALso,I have logged in as root account.

Answer 1

I had a similar problem when I was trying to follow the documentation of EMR.

I solved it by: 1. Creating a user in AWS Identity and Access Management(IAM). 2. After I assigned this user to a 'group'(Create a new group). 2a. The group should have the roles that are being used(S3 and EMR). - Click on attachments and select all the ones are not 0.

I hope this helps you.
