Hi DataEngineer,
The error message you are seeing indicates that the Kusto command task in your Azure Pipeline is unable to resolve the hostname for your Azure Data Explorer cluster. This could be due to a few different reasons, such as a DNS issue or a misconfiguration in your pipeline.
Here are some steps you can take to troubleshoot and resolve this issue:
Check the hostname for your Azure Data Explorer cluster to ensure that it is correct. You can find the hostname in the Azure portal under the "Overview" tab for your cluster.
Check the DNS settings for your Azure Pipeline to ensure that it is able to resolve the hostname for your Azure Data Explorer cluster. You can do this by running the following command in a command prompt or terminal window:
nslookup adx.kusto.windows.net
This command will show you the IP address associated with the hostname for your Azure Data Explorer cluster. If the command is unable to resolve the hostname, there may be an issue with your DNS settings.
Check the firewall settings for your Azure Data Explorer cluster to ensure that they are properly configured to allow traffic from your Azure Pipeline. You can do this by going to the Azure portal, navigating to your Azure Data Explorer cluster, and checking the firewall settings under the "Security + networking" tab.
Check the configuration of your Kusto command task in your Azure Pipeline to ensure that it is properly configured to connect to your Azure Data Explorer cluster. Make sure that the server and database names are correct and that the command is properly formatted.
If none of the above steps resolve the issue, consider opening a support ticket with Microsoft to get further assistance.
I hope this helps you resolve the issue and successfully deploy your ADX tables and functions using your Azure Pipeline.
