KNOX-3003 - Services with more than one serviceUrl metadata are grouped on the
Knox Home page (#838)
> Group UI services of the same type
> ----------------------------------
>
> Key: KNOX-3003
> URL: https://issues.apache.org/jira/browse/KNOX-3003
> Project: Apache Knox
> Issue Type: Improvement
> Components: Homepage
> Affects Versions: 2.0.0, 1.6.0, 1.6.1
> Reporter: Sandor Molnar
> Assignee: Sandor Molnar
> Priority: Critical
> Time Spent: 20m
> Remaining Estimate: 0h
>
> 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)
