@Jitesh Shivnani - Thanks for the question and using MS Q&A platform.

The error message "InvalidNetworkConfigurationErrorCode" usually indicates a problem with the virtual network configuration for your HDInsight Kafka cluster. Based on the rest of the error description, there could be different reasons for the failure.

One possible reason for the error message "Cluster Validation timed out" is that the cluster creation process is taking longer than expected. This can happen if the cluster is large or if there are issues with the underlying infrastructure. In this case, you can try creating the cluster again and see if it succeeds.

Another possible reason for the error message is that there is a problem with the custom DNS configuration. DNS servers within a virtual network can forward DNS queries to Azure's recursive resolvers to resolve hostnames within that virtual network. Access to Azure's recursive resolvers is provided via the virtual IP 168.63.129.16. This IP is only accessible from the Azure VMs. So it won't work if you're using an OnPrem DNS server, or your DNS server is an Azure VM, which isn't part of the cluster's virtual network.

To troubleshoot this issue, you can SSH into the VM that is part of the cluster, and run the command hostname -f. This will return the host's fully qualified domain name. If this command resolves the name to an IP address, it means your DNS server is working correctly. In this case, you can raise a support case with HDInsight, and they will investigate your issue. In your support case, include the troubleshooting steps you executed. This will help them resolve the issue faster.
