YARN-9880. In YARN ui2 attempts tab, The running Application Attempt's ElapsedTime is incorrect.

[cjn082030]

I found this problem where hadoop3.1.1 was used, want to upgrade to the latest version of hadoop, but found the running Application Attempt's ElapsedTime is also incorrect.

In UI1, get ElapsedTime from yarn server. In UI2, get currentTime from brower. Therefore, when the brower and the yarn server are not in the same time zones, the ElapsedTime is incorrect. While the Application‘s ElapsedTime is 29 Secs, the Application Attempt's ElapsedTime is 10 Hrs : 49 Mins : 55 Secs.

I think, in UI2, ElapsedTime should also come from the yarn server too.
