How to collect job metrics in MRv2

Hi MapR team,
We know that metrics db is not supported for MRv2 applications. In MRv1,  job_metrics are stored in metrics db(my sql) and we query the database to get the job_metrics info.. Now, in YARN we are not sure where the job_metrics are stored and how to get the statistics for the same. I see job history server has API but couldn't find the location of metrics on disk. Even documentation doesn't provide this information.

Is there a way where we can collect job metrics (job_id, userid, query, start time, end time etc., )
Any help is appreciated.

Thanks in advance
