>             Project: Spark

>          Components: Scheduler, Spark Core
>    Affects Versions: 2.1.0, 2.1.1, 2.1.2, 2.2.0, 2.2.1, 2.3.0

> Once a fatal error(such as NoSuchMethodError) happens during 
> `onReceive(event)`, the eventThread thread will exist. However the eventQueue 
> is still accepting events. The whole spark application will hang forever.
