Jdbc connection issue / after update 4.1.4

Hi,

after updating to dremio 4.1.4 our clients using an JDBC connector are failing.

I’ve downloaded the driver from the server (dremio/jars/jdbc-driver/dremio-jdbc-driver-4.1.4-202001240912140359-a90eb503.jar).
After connecting with DBeaver I get following error :

[USER]: Channel closed null <–> null (user client)
Failure in connecting to Dremio: cdjd.com.dremio.exec.rpc.RpcException: HANDSHAKE_COMMUNICATION : [USER]: Channel closed null <–> null (user client)
HANDSHAKE_COMMUNICATION : [USER]: Channel closed null <–> null (user client)
HANDSHAKE_COMMUNICATION : [USER]: Channel closed null <–> null (user client)
[USER]: Channel closed null <–> null (user client)
[USER]: Channel closed null <–> null (user client)

Connection URL : jdbc:dremio:direct=server-address:31010
username and password looks correct.

We also have errors when connecting from MicroStrategy clients.

Kind regards,
Geert

Is your JDBC connection SSL based?

Thanks

I’ve the same issue,
Try use driver version 3 even if Dremio server is 4.1.4 and work fine.

Same here.
FYI, I’ve had the same problem with 4.X and 3.3.x drivers. I fell back to 3.0.6 and that solved the problem for me.

Hi everyone, see https://docs.dremio.com/client-applications/tableau-sdk.html#tableau-20203 as this may help resolve the issue for you.

I have the same problem.
did they find a solution?
