> Move DatanodeInfo#hostName to DatanodeID

> Key: HDFS-3164
> URL: https://issues.apache.org/jira/browse/HDFS-3164
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: data-node

> 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.
