    Hi @tdas and @zsxwing , is it feasible to back port this patch to branch 1.4? This patch fixes a restart issue here by updating the state before calling `receiver.onStart()`.
    
    ```scala
    if (onReceiverStart()) {
      logInfo("Starting receiver")
      receiverState = Started
      receiver.onStart()
      logInfo("Called receiver onStart")
    ```
    
    Previously this state is updated after calling `recevier.onStart()`, still will introduce annoying bug in `SocketReceiver` when `restart()` is called.
