Description

Currently, if a UI service has multiple instances with different URLs in a given topology, that UI service will be listed on the Knox Home page as many times as the number of URLs it has. This makes the user experience a lot worse if we are talking about hundreds of occurrences of this case.

We learned from some real-life use cases that IMPALA is one of these services, and there are 1000+ node clusters out there with more than 100 Impala Daemon roles. In that particular case, the Knox Home page was a mess.

To address this issue, the following UI improvement should be implemented:

• if a UI service has more than one URL in the given topology, individual tiles should not be displayed. Instead, one "group" tile must be added with a clear indication this is a group of URLs of the same service.
• clicking the group tile should open a modal window with separate tiles for each service URL
• in this modal window, a search field will be added to give our end-users the chance to narrow down results (by hostname for instance)
