[jira] [Resolved] (SPARK-3949) Use IAMRole in lieu of static access key-id/secret

["Josh Rosen (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SPARK-3949?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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?).

> 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.
