Ming Ma commented on YARN-1756:
-------------------------------
In between newApplication and submitApplication, MR client needs to copy local
jars to HDFS as part of job submission. For applications that submit large
jars, this could take couple seconds or more.
https://issues.apache.org/jira/browse/YARN-1492 will reduce the delta.
> 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.
