Lokesh Jain commented on RATIS-229:
-----------------------------------
Also I think by the time an append entry request times out the server would
have sent other heartbeat requests so we might not even need to trigger a
heartbeat?
> GRpcLogAppender should trigger a heartbeat when appendEntries timeout

> When appendEntries timeout, GRpcLogAppender has already updated
> lastRpcSendTime so that the next heartbeat may not be sent
> immediately.
> This problem is observed in RATIS-227. The killed follower in
> testBasicAppendEntriesWithAllReplication may start a leader election
> after it has been restarted.
