> SwiftNativeFileSystem's directory representation is zero-byte file.
> But in Swift / Horizon, directory representation is a trailing-slash.
> This incompatibility has the following issues.
> * SwiftNativeFileSystem can't see pseudo-directory made by OpenStack Horizon
> * Swift/Horizon can't see pseudo-directory made by SwiftNativeFileSystem. But Swift/Horizon
see a zero-byte file instead of that pseudo-directory.
> * SwiftNativeFileSystem can't see a file if there is no intermediate pseudo-directory
object.
> * SwiftNativeFileSystem makes two objects when making a single directory
> (e.g. "hadoop fs -mkdir swift://test.test/dir/" => "dir" and "dir/" created)
