> RATIS-571, modified the GrpcClientProtocolClient to not set the 
> AsyncStreamObserver reference to null on an exception, however, the ReplyMap 
> reference is set to null. This results in the client getting an 
> AlredyClosedException on the stream on a retry for a NotLeader or a 
> LeadrNotReady exception and never recovers. This is common in a unit test 
> scenario where a request is sent immediately after the cluster is up.
> There is nothing special here about one node Ratis however, the HDDS unit 
> tests that fail are all one node Ratis and the most probable cause is that 
> with client retrying a different node each time, increases the chance of 
> success on a three-node ring.
