> Affects Versions: 3.1.2

> When a executor was not alive, and `ExecutorMonitor` received late `SparkListenerBlockUpdated` event. The `onBlockUpdated` hander will call `ensureExecutorIsTracked`, which will create a new executor tracker with UNKNOWN_RESOURCE_PROFILE_ID for the dead executor. And `ExecutorAllocationManager` will not remove executor with UNKNOWN_RESOURCE_PROFILE_ID, which cause a executor slot is occupied by the dead executor, so a new one cannot be created .
> The ExecutorAllocationManager log was like this:
> 21/08/24 15:38:14 WARN [spark-dynamic-executor-allocation] ExecutorAllocationManager: Not removing executor 34324 because the ResourceProfile was UNKNOWN!
> 21/08/24 15:38:14 WARN [spark-dynamic-executor-allocation] ExecutorAllocationManager: Not removing executor 34324 because the ResourceProfile was UNKNOWN!
