That's my question. I have tried googling but couldn't find clues in the Microsoft documentation. I have my $100 unused, but when I go to HDInsight and try to select the machines type, I cannot select any of them. I always get 0 cores available in every region. I have already enabled Microsoft.Compute as well as Microsoft.HDInsight in my subscription's Resource providers. Should I enable any others?
If it is just not possible at all with a Student subscription, should not it complain from the very beginning (first tab of the process), when I select the subscription for the project in "Project details"?
