> The new NN webUI lists live node at the top of the page, followed by dead
> node and decommissioning node. From admins point of view:
> 1. Decommissioning nodes and dead nodes are more interesting. It is better to
> move decommissioning nodes to the top of the page, followed by dead nodes and
> decommissioning nodes.
> 2. To find decommissioning nodes or dead nodes, the whole page that includes
> all nodes needs to be loaded. That could take some time for big clusters.
> The legacy web UI filters out the type of nodes dynamically. That seems to
> work well.
