    I solved it by adding the parameter AllowSelfSignedServerCert = 1 to the microsoft.impalaodbc.ini file, and that fixed the issue.

     

    I was getting the error:
    ODBC: ERROR [HY000] [Microsoft][DriverSupport] (1100) SSL certificate verification failed because the certificate is missing or incorrect
    This happened after a server update, which now uses a self-signed certificate. I found that unless AllowSelfSignedServerCert is explicitly set to 1 in the microsoft.impalaodbc.ini file, the Microsoft Impala ODBC driver assumes a default value of 0, which causes the SSL certificate verification to fail.

     

    Now my gateway is running fine.
    Thanks to everyone who tried to help!

Hi cgapmmg,

Thank you for being part of the Microsoft Fabric Community.

 

The error message indicates a certificate issue. Please ensure the SSL certificate is correctly placed in the Trusted Root Certification Authorities store for the gateway service account.

Verify the gateway service account has the necessary network and database access, and check firewall settings on the gateway machine and Impala server.

 

Should this information prove useful, kindly mark it as a solution and consider giving us a Kudos.

 

Regards,
Sahasra.
