@nishkamravi2 I suggest that you add a new exception RpcEnvStopException
that extends IllegalStateException. Then you can use RpcEnvStopException in
this line:
https://github.com/apache/spark/blob/7a375bb87a8df56d9dde0c484e725e5c497a9876/core/src/main/scala/org/apache/spark/rpc/netty/Dispatcher.scala#L159
After that, there are two places need to handle this exception:
1. Try-catch RpcEnvStopException in the following line:
https://github.com/apache/spark/blob/7a375bb87a8df56d9dde0c484e725e5c497a9876/core/src/main/scala/org/apache/spark/rpc/netty/NettyRpcEnv.scala#L185
and only log a simple message
2. Check the exception type in the following line:
https://github.com/apache/spark/blob/7a375bb87a8df56d9dde0c484e725e5c497a9876/core/src/main/scala/org/apache/spark/rpc/netty/Outbox.scala#L46
If it's RpcEnvStopException, log a simple message.
