Tsz Wo Nicholas Sze commented on RATIS-201:
-------------------------------------------
Thanks, Lokesh. For testWithLoad, should we pass true for
tolerateMultipleLeaders? The default is false.
{code}
+ RaftServerImpl leader = waitForLeader(cluster, true);
{code}
> MiniRaftCluster#getLeader may incorrectly throw IllegalStateException

> It can be possible for more than one server to have their role set as LEADER
> in a ratis ring. There can be a race condition where term of a follower is
> updated but its role is not yet updated to FOLLOWER. In such a scenario
> MiniRaftCluster#getLeader would throw IllegalStateException.
