Steve Loughran commented on HADOOP-14935:
-----------------------------------------
Other than the issue about "why the special option", patch LGTM, and I like how
you've subclassed TestNativeAzureFileSystemAuthorizationGetFileStatus to
guarantee it runs everywhere. Checkstyle finds an unused import, but that's
something so minor it can be fixed during patch-apply
I'm +1 *pending Thomas being happy*. If he wants more explanations or changes,
that's his call
While waiting for that, why not backport to branch-2 and submit a
HADOOP-14935-branch-2-005.patch for yetus to test on a java7 JVM? It'll make it
much easier to commit to branch-2

> FileSystem implementation class for azure i.e. {{NativeAzureFileSystem}} does
> not override {{access(path,mode)}} method and uses the default implementation
> from the base class. This base implementaion uses the POSIX permissions to
> check if the requested user has access to given path or not even when
> authorization is enabled, which is incorrect.
> {{NativeAzureFileSystem.access()}} in authorization enabled mode should use
> the authorization mechanism provided instead of relying on the POSIX
> permission ons. So the proposal is to override {{FileSystem.access()}} method
> in {{NativeAzureFileSystem}} such that it honors the authorization mechanism
> configured in authorization enabled mode and falls back to POSIX permissions
> otherwise.
