> The javadocs for DiskChecker#checkDir(File dir) trail off, look like they weren't completed,
should be. 
> While checkDir(File) uses java File to check if a dir actually is writable, the version
of checkDir that takes an FsPermission uses FsAction#implies which doesn't actually check
if a dir is writable (eg it passes on a read-only file system). So switching from one version
to the other can cause unexpected bugs. Let's call this out explicitly in the javadocs.
