Subject [jira] [Commented] (HDFS-11198) NN UI should link DN web address using hostnames
Date Wed, 14 Jun 2017 18:27:00 GMT

--------------------------------------

HI [~xiaochen],

Per offline discussion, it seems HDFS-11198 breaks "NameNode UI Datanodes tab", in that case,
we can make the link "broke" instead of just "related to".

Thanks.

> The new NN UI shows links to DN web pages, but since the link is from the info address
returned from jmx, it is in the IP address:port form. This breaks if users are using filters
utilizing cookies.
> Since this is a new feature in 2.8, I didn't mark it as a blocker. I.e. it does not break
any existing functions. It just doesn't work properly in certain environments.
