> During running tasks, when the total number of executors is the value of spark.dynamicAllocation.maxExecutors and the AM is failed. Then a new AM restarts. Because in ExecutorAllocationManager, the total number of executors does not changed, driver does not send RequestExecutors to AM to ask executors. Then the total number of executors is the value of spark.dynamicAllocation.initialExecutors . So the total number of executors in driver and AM is different.
