Is there a proper and/or minimally intrusive way to extend the NameNode web interface of Hadoop (I am using version 2.8.5), for example, by adding a new tab with a view of the cluster in a different way/a way that is specifically tailored to my project? A Hadoop plugin I haven't stumbled upon maybe?

You could find/edit the HTML directly on the nodes. Plugins don't really make sense for HTML – OneCricketeer Sep 20 '20 at 17:18

@OneCricketeer would this require rebuilding the hadoop source and/or restarting the cluster? – Zehanort Sep 20 '20 at 18:29

Not that I know of. I think the namenode UI is just angular code – OneCricketeer Sep 21 '20 at 00:14
