> This could occur when a client is not able to re-auth in time, and the server
> removes the HARegionQueue to the client. When the client is able to re-auth
> later, the new HARegionQueue is created again. There is a race that when the
> server process the above message, the HARegionQueue is not fully initialized
> and cause this NPE.
