Description:
*{{YarnAllocator}}* uses *{{numExecutorsRunning}}* to track the number of
running executor. *{{numExecutorsRunning}}* is used to check if there're
executors missing and need to allocate more.
In current code, *{{numExecutorsRunning}}* can be negative when driver asks to
kill a same idle executor multiple times.
