to start EMR, is KeyName the same as the access key string? I am using accesskey as the arg here: but EMR doesn't accept the access key. I don't see where I can provide a name other than access key:
aws emr create-cluster --name "Kens Test EMR Cluster" ^ --region us-east-2 --release-label emr-5.36.1 --applications Name=Spark ^ --ec2-attributes KeyName=<Access Key String Numbers>^ --instance-type m5.xlarge --instance-count 3 --use-default-roles
AWS EMR docs don't say if it's actually expecting Access Key so not sure
