### Describe the bug, including details regarding any error messages, version, and platform. I am trying to use [parrow.fs.S3FileSystem](https://arrow.apache.org/docs/python/generated/pyarrow.fs.FileSystem.html) in a pod running on AWS EKS. The cluster is configured so that the pod assumes an IAM role via Pod Identity Association. I would like to give an instance of S3FileSystem permanent access to AWS through this IAM role - rather than access using temporary credentials that will expire. I have not found any way to do so. When simply instantiating with no arguments as in `S3FileSystem()`, it has no access to AWS (receives ACCESS_DENIED on `get_file_info` for example). Trying to pass the IAM role that's part of the Pod Identity Association to S3FileSystem using `S3FileSystem(role_arn=...)`, I still get ACCESS_DENIED. I am able to give S3FileSytem access however by passing `access_key, secret_key, session_token` that I obtain from `boto3` - however those credentials will eventually expire. Instead, I am looking to give permanent access to a single S3FileSystem instance. ### Component(s) Python -- This is an automated message from the Apache Git Service.
