Hi @Tim Apps, This is Andrew here from the Zoomdata Support team. I was informed by a colleague that you were encountering some issues and wanted to lend a helping hand! 🙂 You can likely obtain more details about the actual error you're encountering by looking in the zoomdata.log and zoomdata-errors.log files. This can be found in the /opt/zoomdata/logs directory by default. If you are running Zoomdata through docker, you will need to first make sure to SSH into the docker container itself before you'll be able to find these log files. Another quick test that you can run is to try connecting to Hive on Tez using some other SQL query tool from the same docker container where Zoomdata is located. For example, Zoomdata uses a similar hive2 JDBC driver as beeline so if you are unable to connect using beeline, Zoomdata will not be able to connect either. If you are getting errors when trying to use beeline (or said other SQL query tool) and depending on the error thrown, it very well might be some kind of network issue that is preventing the connection from resolving correctly. If the above doesn't work for you, I suggest opening a support ticket with us and we'd be glad to help you further investigate this issue.
