I have stood up a Quickstart Cloudera VM on a PC with all services running allocating 14G of ram. On the desktop that the VM is running on(not in the vm) I installed RapidMiner in order to test out Radoop before it goes onto a production server. I used the "Import from Cluster Manager" from RapidMiner which retrieved the correct configuration from CHD. When I run the full test I am running into a Access denied when rapidminer tests if it can create a table etc on Hive.

Maybe this is just a configuration change I can make in CDH like modify the Hive config, or some way to allow RapidMiner to read/write.
Long story short: on Cloudera Quickstart 5.13 VM you should use the same username for "Hadoop username" on Global tab and "Hive username" and on Hive tab.
