We are using Dremio driver to connect to Dremio and it is having some issues. We even tried using the latest version also but it is giving the same problem.
As a workaround, you can download and extract “dremio.efwd” file from this zip.
DremioEFWD.zip (2.1 KB)
Extract this “dremio.efwd” file and then save it at the location “…\hi\hi-repository\System\Admin\DbConfig”
Once done please restart the server and then you will encouter this error. However with this workaround the problem is it is showing all the schemas at metadata leftmost pane.
