Qi Zhu commented on YARN-10674:
-------------------------------

Thanks [~pbacsko] for patient review, your suggestion is valid.

I have one question:

YARN-10637 also need enable "RM monitors", if we need to set enable "RM 
monitors" default true, because the enable for "RM monitors" has no side 
effect, and the preemption default is false, i think set to true is more 
reasonable.

What's your opinion about this?

Thanks.:D
