> nodetool clearsnapshots failes to delete snapshot directories and exits prematurely causing
the exception at the bottom.
> The actual snapshot files _within_ the directory are correctly deleted but the folder
itself is not deleted.
> I've chmodded all files and folders in the snapshots directory to 777 and rund the command
as root to exclude file permissions as a cause. I also restarted cassandra which has no effect
on the command.
