Tsz Wo Nicholas Sze commented on RATIS-499:
-------------------------------------------
Thanks [~ljain].
# We are already updating orderedStreamObservers in
completeReplyExceptionally(..).
# for a non-leader, the client will get NotLeaderException and then close the
connection.
> Server should close the sliding window if it steps down

> The situation described in RATIS-459 is still possible if a server is not
> restarted. A simple solution is to close the sliding window if there is a
> NotLeaderException. indeed, we should close all client connections when a
> leader steps down.
