Description

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
