MapR Metrics not showing YARN jobs

MapR 4.1.0

I wanted a better view of job / node performance so I thought I would set up a metrics database: http://doc.mapr.com/display/MapR41/Setting+up+the+MapR+Metrics+Database

Now, I get metrics of MapR Classic jobs, but nothing submitted via YARN.

I have installed `mapr-metrics` on my JobTracker and WebServer nodes, pushed `/opt/mapr/conf/db.conf` and `roles/mapr/templates/opt/mapr/conf/hibernate.cfg.xml` to all cluster nodes, and restarted warden.

I can see statistics for Classic Hadoop jobs under Cluster > Jobs but not for YARN jobs.

(Does setting up metrics give me any better visibility into *node* performance?  Not entirely clear.)
