HADOOP-13876 to address multi-bucket test failures separately.
One of the issues is with accessing read-only buckets. If a user accesses a read-only bucket with credentials that do not have DynamoDB write permissions, they will get errors when trying to access the read-only bucket. This manifests causes test failures for ITestS3AAWSCredentialsProvider.
Goals for this JIRA:
- Fix ITestS3AAWSCredentialsProvider in a way that makes sense for the real use-case.
- Document limitations etc. in the s3guard.md site doc.
