> DatanodeID#getName, which returns a string containing the IP:xferPort of a Datanode, is used in a variety of contexts:
> # Putting the ID in a log message
> # Connecting to the DN for data transfer
> # Getting a string to use as a key (eg for comparison)
> # Using as a hostname, eg for excludes/includes, topology files
> Same for DatanodeID#getHost, which returns just the IP part, and sometimes we use it as a key, sometimes we tack on the IPC port, etc.
> Let's have a method for each use, eg toString can be used for #1, a new method (eg getDataXferAddr) for #2, a new method (eg getKey) for #3, new method (eg getHostID) for #4, etc. Aside from the code being more clear, we can change the value for particular uses, eg we can change the format in a log message without changing the address used that clients connect to the DN, or modify the address used for data transfer without changing the other uses.
