> Sometimes YARN graphs, (and summary panel elements sometimes) take long time
> to load. Please look at the videos of the test that failed because it could
> not find the yarn graphs,heatmaps in time.
> I was able to reproduce this issue. STR:
> 1) Go to Yarn service page, but navigate away from it before the graphs are
> loaded
> 2) Try going back again to Yarn page
> The graphs will not load. This was observed on Hbase page as well. Hitting F5
> or Signing back in solves the problem
