    Description

      1. The amResource should be normalized instead of fetching from ApplicationSubmissionContext directly.

          ApplicationSubmissionContext appSubmissionContext =
              rmContext.getRMApps().get(applicationAttemptId.getApplicationId())
                  .getApplicationSubmissionContext();
          if (appSubmissionContext != null) {
              amResource = appSubmissionContext.getResource();
              unmanagedAM = appSubmissionContext.getUnmanagedAM();
          }
      

      2. When one application is removed, the FSLeafQueue's amResourceUsage should be updated only if the app has started its AM.

        if (runnableAppScheds.remove(app.getAppSchedulable())) {
            // Update AM resource usage
            if (app.getAMResource() != null) {
              Resources.subtractFrom(amResourceUsage, app.getAMResource());
            }
            return true;
        }
