Exception: Problem when retrieving bootstrap actions for cluster is seen in the aws_worker daemon logs.

Workaround: While creating AWS account for EMR Chargeback/Insights overview feature, you must include an additional entry in the Policy JSON file for "elasticmapreduce:ListBootstrapActions", as follows:

{
    “Version”: “2012-10-17",
    “Statement”: [
        {
            “Effect”: “Allow”,
            “Action”: [
                “pricing:GetProducts”,
                “elasticmapreduce:ListClusters”,
                “elasticmapreduce:DescribeCluster”,
                “elasticmapreduce:ListInstanceFleets”,
                “elasticmapreduce:ListInstanceGroups”,
                “elasticmapreduce:ListBootstrapActions“,
                “elasticmapreduce:ListInstances”,
                “ec2:DescribeSpotPriceHistory”
            ],
            “Resource”: “*”
        }
    ]
}

Even though the AWS account was already created without this entry (elasticmapreduce:ListBootstrapActions), you can always include this policy later.
