Bo Shi commented on HADOOP-5191:
--------------------------------
I'm not sure if this falls within the scope of this JIRA, but it would be nice
to be able to contact the host thru aliases;
E.g. if the namenode is configured as somehost:9000, and I have somehost mapped
to myalias in my /etc/hosts file, I won't be allowed to connect thru
myalias:9000.
> After creation and startup of the hadoop namenode on AIX or Solaris, you will
> only be allowed to connect to the namenode via hostname but not IP.
