> In federation the configuration files xml include another configuration xml. This configuration xml is empty for datanodes and defines nameservice ID for namenodes, secondary and backup nodes. The need for xml include can be eliminated by namenodes determining the nameservice ID by matching its local address with a configured address (such as namenode rpc address) and on match using the nameservice ID of the corresponding configuration parameter.
