------------------------------------

             Summary: Azure: handle failure gracefully in case of missing account key
                 Key: HDFS-11892

Actually, this error message is not very helpful. I'd admire you if you can immediately find
the root cause of this failure.

If the test account is missing, we simply skip the test with meaningful error message. Here
we should do the same thing: skip the test, and tell the user why we skip it.
