> Components: fs/s3, test
> Affects Versions: 2.8.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Minor

> Surfaced in HADOOP-13518: Intermittent test failure of {{ITestS3NContractRootDir.testRecursiveRootListing}} and {{ITestS3NContractRootDir.testRmEmptyRootDirNonRecursive}}, error text "Can not create a Path from an empty string".
> Looks like theres some confusion creating paths to subdirectories; I'd like to know what's happening before blindly skipping the situation of "empty subdirectory path"
