       The most recommended way is to attach a network security group and a NAT gateway to the subnet. Since the existing subnet which has HDInsight clusters with Azure basic load balancers can't be associated with an NAT gateway due to incompatibility with basic load balancer, there are two scenarios:
 
-      #### Case 1: Existing subnet has no HDInsight clusters with Azure Basic load balancers
