-----------------------------------
Hi [~szetszwo], looks like jira1786 is already resolved. Is this problem
addressed too?
> gRPC installSnapshot timeout handler malfunctioning
> ----------------------------------------------------
>
> Key: RATIS-1782
> URL: https://issues.apache.org/jira/browse/RATIS-1782
> Project: Ratis
> Issue Type: Bug
> Components: gRPC, snapshot
> Affects Versions: 2.4.1
> Reporter: Song Ziyang
> Assignee: Xinyu Tan
> Priority: Blocker
>
> When gRPC logAppender fails to install a snapshot to a follower owing to
> timeout, the onError callback will be invoked and resetClient is called.
> However, in this resetClient[1] handler, installSnapshotResponseHandler is
> not set to null (compared to appendLogReponseHandler). In this way, pending
> RPCs in the old installSnapshot pipe will timeout and call the onError again
> sometime in the future, disrupting future on-going installSnapshot requests.
