> Currently limitations in Sun's KerbSSL implementation require the https server to be
run as "host/[machine]@realm." and another Sun KerbSSL limitation appears to require you to
store all principals in the same keytab, meaning fully functional, secured Namenodes require
combined keytabs.  However, it may be that one wishes to run a namenode without a secondary
namenode or other utilities that require https.  In this case, we should allow the http server
to start and log a warning that it will not be able to accept https connections.
