Sunil Govindan commented on YARN-8466:
--------------------------------------
Thanks [~leftnoteasy] for proposing this and [~cheersyang] for good insights.
In my opinion, we were seeing a few issues when nodes are added/removed in
sync/async scheduling and metrics etc going wrong. So having a system which can
check with various invariants will ensure that any new patch which comes in is
not breaking some metrics etc. It will be great to collaborate and get this as
a common test system which can extend this to a distributed system.
