• Type: Bug

Description

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)
