> This patch implements Owen's comments to HADOOP-321. Namely,
> - Namenode.sendHeartbeat does not create a throwaway DatanodeDescriptor. DatanodeID is
sufficient in this case.
> - DatanodeID is made Writable, and it also implements equals() and hashCode().
> - DatanodeInfo is updated to call base class methods in its implementation of Writable
interface.
> - I changed the way strings are written/read using UTF8.writeString and UTF8.readString.
> - Some comments are updated.
