> Path converts "\" into "/", probably for windows support?  This means it's impossible
for the user to escape metachars in a path name.  Glob expansion can have deadly results.
> Here are the most egregious examples. A user accidentally creates a path like "/user/me/*/file".
 Now they want to remove it.
> {noformat}"hadoop fs -rmr -skipTrash '/user/me/\*'" becomes...
> "hadoop fs -rmr -skipTrash /user/me/*"{noformat}
> * User/Admin: Nuked their home directory or any given directory
> {noformat}"hadoop fs -rmr -skipTrash '\*'" becomes...
> "hadoop fs -rmr -skipTrash /*"{noformat}
> * User:  Deleted _everything_ they have access to on the cluster
> * Admin: *Nukes the entire cluster*
> Note: FsShell is shown for illustrative purposes, however the problem is in the Path
object, not FsShell.
