> As the title describes the problem:  if the include host list contains host name, after
restarting namenodes, the datanodes registrant is denied by namenodes.  This is because after
namenode is restarted, the still alive data node will try to register itself with the namenode
and it identifies itself with its *IP address*.  However, namenode only allows all the hosts
in its hosts list to registrant and all of them are hostnames. So namenode would deny the
datanode registration.
