Hi @John Cleveland Both the popular HDP and HDF Sandboxes are delivered as Dockerized containers. You are correct that there is a Docker container, as well as a Host machine that are different but ship within the same VM appliance. The following link from the docs might help provide additional clarity as well: https://hortonworks.com/tutorial/hortonworks-sandbox-guide/section/2/

hi @John Cleveland If you are using the HDF VirtualBox sandbox, you should be able to boot the machine and follow the Getting To Know the Sandbox guide here: https://hortonworks.com/tutorial/getting-started-with-hdf-sandbox/ I don't recall having to do any setup via scripts, just point my browser to the NiFi UI (http://sandbox.hortonworks.com:19090/nifi) Can you reach the NiFi URL after booting the machine?

Good to know that your issue is resolved. Few details: hadoop.proxyuser.<USER>.hosts From File View perspective: Here we need to replace the <USER> with the username who is actually running the Ambari Server (Or Standalone Ambari FileView Server) . So if you are running ambari server as "root" user then you will need to set the property for "root" user as "hadoop.proxyuser.root.groups". The Value of this property can be a comma separated list of addresses where you are running the ambari server (OR Standalone View Ambari Server for hosting the View) . Because View Server will actually send requests to Hadoop. So hadoop need to allow access from the host where the FileView is running. Setting * means you can use the FileView (Standalone Ambari View Server) which is installed to any host. (In a kerberized environment we need to replace the <USER> with the ambari server kerberos principal name). From Generic Hadoop Perspective: In general, By Using proxy user using properties "hadoop.proxyuser.$superuser.hosts" along with either or both of "hadoop.proxyuser.$superuser.groups" and "hadoop.proxyuser.$superuser.users".
By specifying as below in core-site.xml, the superuser named super can connect only from host1 and host2 to impersonate a user belonging to group1 and group2.
Following document explains it with examples: https://hadoop.apache.org/docs/r2.7.3/hadoop-project-dist/hadoop-common/Superusers.html

I have gotten the demo to work. 1. I needed to insure that both kafka and storm were working. Kafka would not start because I did not have enough memory allocated to the VM. So I gave the VM 16G of memory. 2. I had to log in to ambari administrator as maria_dev or raj_ops. There is a link to set the passwd for admin. So I changed the passwd to admin. 3. Works
