Fengnan Li commented on HDFS-15757:
-----------------------------------
Thanks for the review [~elgoiri] There are two metrics we will try to improve.
1. RpcClientNumConnections should go down in each router
2. RpcClientNumActiveConnections / RpcClientNumConnections should go up in each
router.
I will add more graphs for this in an updated doc. The first version was trying
to get some initial feedback.
