> The following scenario was tested:
> * Determine Active NN and suspend the process (kill -19)
> * Wait about 60s to let the standby transition to active
> * Get the service state for nn1 and nn2 and make sure nn2 has transitioned to active.
> What was noticed that some times the call to get the service state of nn2 got a socket
time out exception.
