Thats ok.. It does miss ITestS3Guard{ListConsistency, ToolDynamoDB}, FYI, but
you got most of the tests.

2. ITestS3ACredentialsInURL#testInstantiateFromURL is not supported. Should we
simply skip this test if the metadata store is enabled (in a separate JIRA)?
{quote}
Yes. Nothing new here and we do need to fix it.

3. ITestS3AEncryptionSSEC started failing after merge because of the strict
exception message assertion; it is fine in trunk. The only change is to remove
"Forbidden" word as it would be "Access Denied" sometimes along with the same
exception class java.nio.file.AccessDeniedException and message Service: Amazon
S3; Status Code: 403; Error Code: AccessDenied;. For this I made the change
when merging.

Sounds ok. Curious, what is our difference in HADOOP-13345 that changes this?
Is our feature branch exception behavior different?
