Define roles in Amazon EMR

You need to define the Service role and Job flow role in Amazon EMR before starting an Amazon EMR cluster.


  1. Follow the instructions in the Default IAM roles for Amazon EMR documentation to define the roles. This will create the EMR_DefaultRole and the EMR_EC2_DefaultRole that will be used to launch an Amazon EMR cluster from Talend Studio.
  2. From your AWS Management Console, navigate to the Identity&Access Management service.
  3. In the left menu, click Roles and check that your roles have been successfully created.
