Josh Rosen resolved SPARK-3949.
-------------------------------
Resolution: Incomplete
As of SPARK-8576, spark-ec2 can launch instances with IAM instance roles. I'm
going to close this issue as "Incomplete" since it's underspecified; it would
be helpful to know more specifically where you think we need support for IAM
roles instead of keys (i.e. while launching the cluster? for configuring access
to S3?).
> Use IAMRole in lieu of static access key-id/secret

> Key: SPARK-3949
> URL: https://issues.apache.org/jira/browse/SPARK-3949
> Project: Spark
> Issue Type: Improvement
> Components: EC2
> Affects Versions: 1.1.0
> Reporter: Rangarajan Sreenivasan
>
> Spark currently supports AWS resource access through user-specific
> key-id/secret. While this works, the AWS recommended way is to use IAM Roles
> instead of specific key-id/secrets.
