The subscription being used exceeds the cpu cores

Question

I keep on getting the above message when I am trying to set up a new HDInsight HBase cluster.

However I am only trying to use 1 core in the new cluster and according to the Azure portal (when I go to Settings-Usage (see screenshot below) I am using 0% of 40 cores.

Does anybody know how to resolve this?

HDInsight core limits are calculated separately from the cores that are shown in the Settings-Usage tab. If you click on one of your existing HDInsight clusters, you should see a graphic that outlines the cores used by that cluster, as well as the total cores used and the overall limit, similar to:

Alternately you can use Azure Powershell's Get-AzureHDInsightProperties cmdlet to list the cores used/available in your subscription.

Keep in mind that the number of cores uses is based on the CPU cores of all of the VMs included in the cluster. For example, a 2 data node cluster will actually use 16 cores (Two A3 Head Nodes with 4 cores each and two A3 Data Nodes with 4 cores each). The VM sizes can vary depending on configuration options and cluster type. Details on the VM sizes included in a cluster can be seen at: http://azure.microsoft.com/en-us/pricing/details/hdinsight/

If you need additional cores allocated for your subscription, open a case with Support Type=Billing at https://manage.windowsazure.com/?getsupport=true and then select "Quota or Core Increase Requests" as the problem type, and "HDInsight" as the category.
