Gabor Bota commented on HADOOP-15799:
-------------------------------------
Ok, so I think I've figured out the issue - I had the failure with the test run
when {{fs.s3a.s3guard.test.authoritative}} is false, so I don't pass the
{{-Dauth}} flag and run it via CLI mvn. To fix this, we should add something
like a
{code:java}
Assume.assumeTrue("MetadataStore should be capable for authoritative "
+ "storage of directories to run this test.",
isMetadataStoreAuthoritative(ms));
{code}
To {{ITestS3AEmptyDirectory}}, so skip the test if the ms is not authoritative
instead of failing.

> I've seen a new failure when running verify for HADOOP-15621. First I thought
