      Description

      HDFS-3990 is a change that optimized some redundant DNS lookups. As part of that change, DatanodeManager#registerDatanode now rejects attempts to register a datanode for which the name has not been resolved. Unfortunately, this broke single-node developer setups on Windows, because Windows does not resolve 127.0.0.1 to "localhost".
