> Like HDFS-3138 (the ipcPort) the hostName field in DatanodeInfo is not ephemeral and
should be in DatanodeID. This also allows us to fixup the issue where the DatanodeID#name
field is overloaded (the DN sets it to a hostname, then the NN clobbers it with an IP, and
then the DN clobbers it's hostname field with this IP). If the DN can specify both a "name"
and "hostname" in the DatanodeID then this code becomes simpler.
