In
               most cases, all SAS LASR Analytic Server instances stop automatically
               if communication with any machine in the cluster fails. However, if
               any servers are still running, stop them.
               
            
 
            
            Stop SAS High-Performance Deployment of Hadoop
               to avoid logging messages about the machine being unavailable. For
               SAS Visual Analytics deployments, stop the SAS LASR Analytic Server
               Monitor, too.
