Subject [jira] [Commented] (YARN-7088) Fix application start time and add submit time to UIs
Date Thu, 31 Aug 2017 13:37:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7088?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16148980#comment-16148980

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.
