Allen Wittenauer commented on HADOOP-6364:
------------------------------------------

I don't know.  I've never tried it since it is undocumented. :)

> There was a bit of talk about HDFS-34 last night at Apachecon.  One of the points brought
up was the difficulty in assuming that the 'hostname' was externally available.  Perhaps what
needs to happen instead is to follow what httpd and a few other apps do.  That is provide
a way for the service to know what hostname to advertise itself as and use in all communications.
 This could also help solve the multi-nic problems (HADOOP-6210) faced when using hadoop in
a HA environment.
