--------------------------------------
Thanks for your comment, Gera. Yes, I'm creating patch based on exit code
approach. The work is almost done. I'm writing test code to verify.

> FairSchedulerAppsBlock#render throws NPE at this line
> {code}
> int fairShare = fsinfo.getAppFairShare(attemptId);
> {code}
> This causes the scheduler page now showing the app since it lack the
> definition of appsTableData

> Uncaught ReferenceError: appsTableData is not defined
> {code}
> The problem is temporary meaning that it is usually resolved by itself either
> after a retry or after a few hours.
