             Summary: General usability improvements in showSimulationTrace.html
                 Key: YARN-9836
                 URL: https://issues.apache.org/jira/browse/YARN-9836
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: scheduler-load-simulator
    Affects Versions: 3.3.0
            Reporter: Adam Antal
            Assignee: Adam Antal


There are some small usability improvements that can be made for the offline analysis page (showSimulationTrace.html):
- empty divs can be hidden until no data is displayed
- the site can be refactored to be responsive given that bootstrap is already available as third party library
- there's no proper error handling in the site (e.g. a JSON is malformed and similar cases) which is really a big problem
- there's no indentation in the raw html file which makes supportability even worse
