public interface DNSToSwitchMapping
An interface that should be implemented to allow pluggable
DNS-name/IP-address to RackID resolvers.
Resolves a list of DNS-names/IP-addresses and returns back a list of
switch information (network paths).
List<String> resolve(List<String> names)
- Resolves a list of DNS-names/IP-addresses and returns back a list of
switch information (network paths). One-to-one correspondence must be
maintained between the elements in the lists.
Consider an element in the argument list - x.y.com. The switch information
that is returned must be a network path of the form /foo/rack,
where / is the root, and 'foo' is the switch where 'rack' is connected.
Note the hostname/ip-address is not part of the returned path.
The network topology of the cluster would determine the number of
components in the network path.
