Eli Collins commented on HDFS-3932:
-----------------------------------
- Rather than loop through IPs I think it would be better to use
DNS#getDefaultIP("default"). This may return the loopback IP eg on a developer
local install but that's OK because that would be a valid IP to use on a
developer local install anway. IIUC on real clusters we require this not be the
loopback. We should add a wrapper so you can just call DNS#getDefaultIP().
- The javadoc doesn't match the implementation (it says use the hostname)
- The test should check all the cases the code checks (multicast, link-local
and loopback here, but see above about not checking loopback)
> NameNode Web UI broken if the rpc-address is set to the wildcard

> If {{dfs.namenode.rpc-address}} is set to the wildcard some of links in the
> dfsnodelist.jsp and browseDirectory.jsp pages are broken because the nnaddr
> field is passed verbatim (eg nnaddr=0.0.0.0:8021).
