Hello,
I'm trying to configure EMR clusters launched with mrjob with custom EMR-managed security groups (that is, pre-existing customized master/slave security groups that EMR then adds its managed rules to). As far as I can tell, there used to be an `emr_api_params` mrjob option that might have been a good workaround here, but that was removed as of v0.7.0 (for what it's worth I'm currently on v0.6.6 but I'd rather not start depending on something that's actually removed a couple versions forward). I can't find any mrjob support for the `--ec2-attributes` cluster creation param that this would be under if calling AWS directly, and `emr_configurations` isn't the right place as far as I can tell. Does anyone have any advice for how to proceed? Also FWIW I'm aware that I can just have EMR automatically create its managed security groups and then manually edit them after the fact with whatever custom rules I want, but I'm trying to avoid that since I can automate the pre-creation with Terraform.
Thanks so much,
Ariel
