After executing the
DeleteCluster()
method, you can go back to the Azure portal and confirm that the
AutomatedHDICluster
, which we just provisioned through code, no longer exists. You see only the two clusters that
were previously created, as shown in Figure
4-8
.

AutomatedHDICluster is deleted
Using the HDInsight management package, you can easily list, create, and delete your HDInsight clusters on
Azure. Add a call to the functions we added earlier inside the
Main()
method, and call them sequentially to view the
output in the console window. The complete code listing for the
Program.cs
file along with the
Main()
method is
provided in Listing 4-5.
