> DatanodeManager#registerDatanode checks the host to node map using an IP:port
> key, however the map is keyed on IP, so this check will always fail. It's
> performing the check to determine if a DN with the same IP and storage ID has
> already registered, and if so to remove this DN from the map and indicate
> that eg it's no longer hosting these blocks. This bug has been here forever.
