Unable to connect via ODBC

I have installed the Apache Arrow Flight SQL ODBC driver.
In the ODBC manager I entered the IP address of the server and used the proper credentials. All other settings were left as default.

I have added the following to my dremio.conf file:
flight: {
enabled: true,
port: 32010,
auth.mode: “legacy.arrow.flight.auth”
} and restarted Dremio.

I am getting to following error:

Flight returned unavailable error, with message: failed to connect to all addresses. Please ensure your encryption settings match the server.

We are using Community Edition, Build: 21.2.0-202205262146080444-038d6d1b

Have you tried with version 22?

https://docs.dremio.com/software/drivers/arrow-flight-sql-odbc-driver/
Starting with Dremio v22.0, you can use the ODBC driver for Arrow Flight SQL to connect to Dremio from ODBC client applications.

Download the open source ODBC Driver for Apache Arrow Flight SQL to connect to Dremio version 22.0+ or any other database that exposes an Arrow Flight SQL endpoint.

So I upgraded to version 22 from version 21 and ran dremio-admin upgrade. I get the following output:
KVStore version is 22.0.0-202206221430090603-1fa4049f

and now when I restart dremio it didn’t retain any of the user data or connections or reflections.

I still have the /data folder from version 21 archived. How do I upgrade and keep the previous data?

We have upgraded to Community Edition version 22 and are still unable to connect via ODBC with the Arrow Flight driver.

“Flight returned unavailable error, with message: failed to connect to all addresses. Please ensure your encryption settings match the server.”

@summersmd , are you trying to connect to the Arrow Flight service (default port 32010). One thing to watch out for is that the driver now assumes you are using encryption by default. To turn it off, set the UseEncryption property to false.

You should not use the legacy auth mode as well.

I have authentication turned off in the ODBC manager. What do you mean by legacy auth mode?

The “auth.mode” option in your dremio.conf. Delete this line or set it to “arrow.flight.auth2”.

I tried changing the line to “arrow.flight.auth2” and got the same error message. Then I deleted that line and restarted dremio and still got the same error.
