胡振宇 updated SPARK-36584:
------------------------
Description:
When driver broadcast object, it will send the
[SparkListenerBlockUpdated|https://github.com/apache/spark/blob/df0ec56723f0b47c3629055fa7a8c63bb4285147/core/src/main/scala/org/apache/spark/scheduler/SparkListener.scala#L228]
event.
[ExecutorMonitor#onBlockUpdated|https://github.com/apache/spark/blob/df0ec56723f0b47c3629055fa7a8c63bb4285147/core/src/main/scala/org/apache/spark/scheduler/dynalloc/ExecutorMonitor.scala#L380]receives
and handles the event, in this method,
it calls [ensureExecutorIsTracked|#L489]
to put driver in `executors` variable with `UNKNOWN_RESOURCE_PROFILE_ID`. In
my understanding, `ExecutorMonitor` should only monitor Executor. Although
this will not cause any problems at the moment because
UNKNOWN_RESOURCE_PROFILE_ID will be filtered out, but I think this is a
potential risk
