-----------------------------------------
Summary: GrpcClientProtocolService should close connection for
NotLeaderException
Key: RATIS-504
URL: https://issues.apache.org/jira/browse/RATIS-504
Project: Ratis
Issue Type: Bug
Components: gRPC
Reporter: Tsz Wo Nicholas Sze
Assignee: Tsz Wo Nicholas Sze
When a server is a follower, clients can still send requests to it. The server
will response NotLeaderException. It is possible that the server may later
become a leader. As a result, the server may replies NotLeaderException for
some earlier requests when it is not yet the leader, and then processes some
later requests after it becomes the leader. It violates the ordering guarantee.
