/**
 * Exception which Hadoop's AWSCredentialsProvider implementations should
 * throw when there is a problem with the credential setup. This
 * is a subclass of {@link AmazonClientException} which sets
 * {@link #isRetryable()} to false, so as to fail fast.
 * This is used in credential providers and elsewhere.
 * When passed through {@code S3AUtils.translateException()} it
 * is mapped to an AccessDeniedException. As a result, the Invoker
 * code will automatically translate
