>   In Hadoop IPC Client, we are using ClientCache which will maintain the HashMap to keep
the Client references.
> private Map<SocketFactory, Client> clients =
>       new HashMap<SocketFactory, Client>();
>  Now let us say, we want use two standard factories with Hadoop. MyStandardSocketFactory
(which extends StandardSocketFactory), and StandardSocketFactory. In this case, because of
equals and hashcode implementation, MyStandardSocketFactory client can be overridden by StandardSocketFactoryClient
