@andrewor14 Now i have a problem. For example, there is three executors.
After same minutes, There executors will be removed because of no recent
heartbeats. Before new executor be registered, the tread
spark-dynamic-executor-allocation sends killExecutor to driver because
executors has been idle for 60 seconds. Then driver will send RequestExecutors
to AM, and change a total number of executors requested by Driver. So the
number is different with ExecutorAllocationManager.
