Why did you have to copy the jdbc jar to the jars folder. Are you using the same host as a JDBC client, then you have to copy the JDBC jar to the client application’s library or jars folder, like for example if you want to use DBeaver then follow JDBC using DBeaver

Thanks for your response, you are right, I described wrong, I copied the dremio jdbc jar file to the apache Drill jars/3rdparty folder and jdbc-driver folder, since the drill is the client to access dremio. for some reason, I re-installed the dremio and this error disappeared, but there is a table not found error, I started with a new topic for this error.

Thanks
