>   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
