胡振宇 updated SPARK-36584: ------------------------ Description: When driver broadcast object, it will send the [SparkListenerBlockUpdated|#L228] event. [ExecutorMonitor#onBlockUpdated|#L380]] receives and handles the event, in this method, it calls [ensureExecutorIsTracked|#L489] to put driver in `executors` variable, but in my understanding, `ExecutorMonitor` should only monitor Executor, not Driver. Moreover, adding a `driver` to the `executors` will affect the calculation of [ExecutorAllocationManager#removeExecutors|#L552]], and the driver will occupy the count of `executors` was: When driver broadcast object, it will send the [SparkListenerBlockUpdated|#L228]] event.
