Has there been any update with regards to this? I, too, am getting the “S020 Data storage error” when executing “Explain” in section 2.6 of the Getting Started tutorial (http://hortonworks.com/hadoop-tutorial/hello-world-an-introduction-to-hadoop-hcatalog-hive-and-pig/#section_8).
I am running the HDP Sandbox on Azure with an A4 instance as per the instructions.
