Jakob Homan commented on HDFS-1477:
-----------------------------------
The addInternalServlet call is used for machine-to-machine servlets that users
won't use and are not authenticated (or are authenticated over kerberos). This
servlet should use the standard add call so that in a secure system the user
will be authenticated. Haven't reviewed the rest of the patch; just wanted to
throw that out.
> Make NameNode Reconfigurable.
