we are trying to set-up an arrow flight connection between a docker instance of Dremio on one server and our “Python server”. When testing our connection, we run into following authentication issue:
<span< a="" style=“box-sizing: unset;”>FlightUnauthenticatedError: gRPC returned unauthenticated error, with message: </span<>.
We want to benchmark running a query through odbc vs arrow flight. The odbc-connection works as expected, but we couldn’t find anything about arrow flight in docker documentation, so we decided to experiment with port 32010. We are able to create a connection (gRPC), but not receive data. We believe this is related to arrow-configuarion (legacy vs new), but we are not able to change any configuration within the container.
Can you give us any advice on how to set up arrow flight from within a container?
docker image dremio/dremio-oss: v13.1.0
If needed we can give more details about our Python environment.
