-----------------------------------

             Summary: log from GrpcLogAppender is confusing
                 Key: RATIS-1543
                 URL: https://issues.apache.org/jira/browse/RATIS-1543
             Project: Ratis
          Issue Type: Bug
          Components: gRPC
            Reporter: George Huang


log is confusing, sample log:

:
|11:50:33.405 PM|WARN|GrpcLogAppender|b10a9cc8-27da-465f-88b6-b018f1f3e120@group-36C03A05E474->922c1eba-d889-4ab5-a291-13a39d4cf47f-GrpcLogAppender: Leader has not got in touch with Follower b10a9cc8-27da-465f-88b6-b018f1f3e120@group-36C03A05E474->922c1eba-d889-4ab5-a291-13a39d4cf47f(c-1,m0,n54227, attendVote=true, lastRpcSendTime=0, lastRpcResponseTime=391556447) yet, just keep nextIndex unchanged and retry.|

In this case, here is the leader and follower info:

LEADER:b10a9cc8-27da-465f-88b6-b018f1f3e120

FOLLOWER:922c1eba-d889-4ab5-a291-13a39d4cf47f

Seems the corresponding code is at here:

:

if (onError && getFollower().getMatchIndex() == 0 && request == null) {
LOG.warn("{}: Leader has not got in touch with Follower {} yet, " +
"just keep nextIndex unchanged and retry.", this, getFollower());
return;
}
