Currently when NN failover happens, the old SBN first sets its state to active, then starts the active services (including tailing all the remaining editlog and building a complete retry cache based on the editlog). If a retry request, which has already succeeded in the old ANN (but the client fails to receive the response), comes in between, this retry may still get served by the new ANN but miss the retry cache.
