bq. Maybe we need to notify the other streamers this remote exception.
Yes. And maybe another option is, instead of letting the DataStreamer threads
doing the RPC to NN for the next block, we can let the main thread do the RPC
(maybe during {{writeChunk}}) and all the streamer threads just wait for the
result. In this way we may simplify the current logic as well. Let me explore
more in the direction today.
