Not sure if this is the correct place to post but hopefully it saves someone else some of the frustrations I’ve recently had…
After moving our Dremio instance to a new VM I found I was no longer able to connect to a database on MS SQL Server. I eventually realised that the JDK point releases were different between the two machines and that OpenJDK 1.8.0.312 (the current release at time of writing) was the culprit.
I changed to a different point release and was then able to connect to MS SQL Server.
