Steve Loughran commented on HADOOP-14151: ----------------------------------------- # it's a duplicate of an existing issue; I think you will be able to find it # it's essentially how directories are mocked in it, in a way which cyberduck & c can handle # You could try to see if using a "/" can be used instead One thing which can be done is make sure that swift kills parent mock directories after file and directory create; S3A optimisations show how to do this best: don't waste time doing HEAD requests, just DELETE each one (though as s3 supports a bulk delete, it's more efficient here) > Swift treats 0-len file as directory > ------------------------------------ > > Key: HADOOP-14151 > URL: https://issues.apache.org/jira/browse/HADOOP-14151 > Project: Hadoop Common > Issue Type: Bug > Components: fs/swift > Affects Versions: 3.0.0-alpha3 > Reporter: John Zhuge > > Unit test {{TestSwiftContractRootDir#testRmNonEmptyRootDirNonRecursive}} > fails at {{assertIsFile(file)}}. This leads me to suspect swift treats 0-len > file as directory.
