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:
