Review comment:
I am not sure how widely this is used, particularly as it is not enabled
by default.
Especially in context of dynamic resource allocation, it can become very
chatty when executor's start getting dropped.
Given this, I am not very keen on enabling it atleast for yarn. Thoughts
@tgravescs ?
