> 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.
