Eric Yang commented on YARN-9809:
---------------------------------
[~Jim_Brennan] This feature is a great addition to make admin task easier for
large scale cluster. What is the latency that we are talking about in
health-check script? If it is a few seconds and less, I agree that there is
marginal difference in startup time, and potential benefit is great.
