This template allows you to create an secure Azure VNet and a HDInsight cluster within the VNet. Azure Virtual Network allows you to extend your Hadoop solutions to incorporate on-premises resources such as SQL Server, combine multiple HDInsight cluster types, or to create secure private networks between resources in the cloud. The template creates a network security group (including the inbound security rules), a virtual network, an HDInsight Hadoop cluster and the default storage account. Please note the rules are "all other regions" listed in Extend HDInsight capabilities by using Azure Virtual Network( https://docs.microsoft.com/en-us/azure/hdinsight/hdinsight-extend-hadoop-virtual-network). You can either use a region other than Brazil South, Canada East, Canada Central, West Central US, and West US 2, or modify the IP addresses defined in the rules.
