Íñigo Goiri commented on HDFS-15757:
------------------------------------
Thanks [~fengnanli] for the updates.
I think it would be possible to do kind of A/B testing and have a set of
Routers with the proposed changes and another set without it.
This would show the metrics improving clearly.
Would that be possible?
