> Scenario:
> We want enable NN dfs.namenode.servicerpc-address to separate the client and DN RPC,and
do it begin with standby NN--just add the property to standby NN and DNs,when EditLogTailer
choose active NN address,it only reset the active NN's nnId generic keys ,but don't unset
if not special,so the standby NN choose itself as active NN.
