Eli Collins commented on HADOOP-8804:
-------------------------------------
This patch still prints "NameNode '0.0.0.0:18021' (active)", just adds more
info wrt hostname which I don't think is necessary. I'd actually go with option
#4 and leave the HDFS side alone for now since it's the best of the current UIs
and improve the RM, JT, NM side since they're worse, eg "0 Hadoop Map/Reduce
Administration" eg make them consistent could be "JobTracker '0.0.0.0:50030'"
to match.
(Btw checked out the patch, should use InetAddress methods rather than check
for address constants as strings, eg "0.0.0.0", which only matches ipv4
wildcard).
> Improve Web UIs when the wildcard address is used

> When IPC addresses are bound to the wildcard (ie the default config) the NN,
> JT (and probably RM etc) Web UIs are a little goofy. Eg "0 Hadoop Map/Reduce
> Administration" and "NameNode '0.0.0.0:18021' (active)". Let's improve them.
