Steve Loughran updated HADOOP-10948:
------------------------------------
Status: Patch Available (was: Open)
resubmitting.
What are we do do here? The 0-byte pseudo dir went copying s3n; this swift
pseudo-dir thing seems a swift-specific feature. It's obviously better, but has
implications for backwards compatibility.

> 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)
