-----------------------------------
Hi [~hanishakoneru], thanks for reporting this problem. I tried to reproduce
it in a unit test but the test passed. In the new test,
# a single node cluster is started;
# client write some messages to the cluster
# call setConfiguration() to add one more node
# sleep 5s
# start the new peer
> Cannot add new node to single node Ratis ring
> ---------------------------------------------

> We cannot add a new node to a single node raft ring. The setConfiguration
> request times out as it does not get a quorum (2 nodes in the ring but the
> 2nd new node has not started up yet). The timeout is very less to start the
> 2nd node to startup and respond to the setConfiguration request.
