Zhijie Shen commented on YARN-1756:
-----------------------------------
What does "newApplication" meaning? Constructing the RMAppImpl instance? AFAIK,
submitTime is captured in ClientRMService, and before constructing the
instance, there's just a few step of sanity check. Therefore, the "newTime"
will be quite close to submitTime.
> capture the time when newApplication is called in RM

> The application submission time ( when submitApplication is called) is
> collected by RM and application history server. But it doesn't capture when
> the client calls newApplication method. The delta between newApplication and
> submitApplication could be useful if the client submits large jar files. This
> metric will be useful for https://issues.apache.org/jira/browse/YARN-1492.
