Steve Loughran commented on HADOOP-13162:
-----------------------------------------
When writing tests, imagine "what information would I need to debug this if it
failed on jenkins". All asserts need meaningful messages.
Here'd I'd actually use {{ContractTestUtils.assertIsDirectory()}} which gives
the message and the full filestatus on a failure
> Consider reducing number of getFileStatus calls in S3AFileSystem.mkdirs

> getFileStatus is relatively expensive call and mkdirs invokes it multiple
> times depending on how deep the directory structure is. It would be good to
> reduce the number of getFileStatus calls in such cases.
