/**
* AnonymousAWSCredentialsProvider supports anonymous access to AWS services

* for most cases, because allowing anonymous access to an S3 bucket compromises
* security. This can be useful for accessing public data sets without
* requiring AWS credentials.

* Please note that users may reference this class name from configuration
* property fs.s3a.aws.credentials.provider. Therefore, changing the class name
* would be a backward-incompatible change.
