Sunil G commented on YARN-7088:
-------------------------------
{code}
184 this.pendingTime = Times.elapsed(app.getStartTime(),
185 app.getLaunchTime());
186 this.elapsedTime = Times.elapsed(app.getLaunchTime(),
187 app.getFinishTime());
{code}
*elapsedTime* could depend on scheduler wait queue as we discussed. I guess
*pendingTime* is indicated as time between app start from RM and its
registration time. If app is registered later, this value at time may not be
very small in seconds.
Since we need to project time different between "app start" and "app
registration", *pending* is still vague. Even if the length of variable a
little bigger and if it serves a better readability, i think it might be fine.

> Currently, the start time in the old and new UI actually shows the app
> submission time. There should actually be two different fields; one for the
> app's submission and one for its start, as well as the elapsed pending time
> between the two.
