Bikas Saha commented on HADOOP-8973:
------------------------------------
On branch-1-win internally winutils would be used to infer the Windows ACL's
into rwx permissions. If those changes have been ported over then it should
work on Windows too. Other places use similar logic which can be checked by
looking for references to the FsAction.implies() method.
> DiskChecker cannot reliably detect an inaccessible disk on Windows with NTFS

> DiskChecker.checkDir uses File.canRead, File.canWrite, and File.canExecute to
> check if a directory is inaccessible. These APIs are not reliable on Windows
> with NTFS ACLs due to a known JVM bug.
