Hi all, I just updated the code according to your comments, please help to
review, thanks a lot. There's two opening questions I didn't address yet:
1. Do we need to set the `initializing` flag to false when the initial
executors have all registered. There's a concern as I mentioned before, there's
a window for Yarn to ramp down the executors when all the initial executors are
registered, but user job has not yet submitted and executor is not timeout, I'm
not sure is this a intended behavior?
2. Do we need to change the code to not send request when the old
`numExecutorsTarget` is equal to new calculated one in all the situations (when
initializing is finished)?
Please help to address the concern, thanks a lot and appreciate your time.
