Description

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.
