PowerBI DirectQuery to Kerberised Impala + bug

Hi   Does PowerBI support DirectQuery for Impala sitting on a kerberised hadoop cluster?   From what I can understand the answer is no (referring to: https://ideas.powerbi.com/forums/265200-power...

    stuartjmccoll,

    Yes, this is a known issue for some connectors. Fix is planned in February release of Power BI Desktop on Feb 5th, 2018.

    In your scenario, check if you can use previous Power BI Desktop to connect to Impala with DirectQuery mode.

While the support for DirectQuery in a Kerberos enabled environment isn't released, you can configure your Impala service to authenticate with LDAP.

The impala service will use the authenticated LDAP user for authorization (sentry) and the impala service principal to access the cluster resources.

With this configuration, we're able to use DirectQuery + Impala + Kerberos.

 

You can find more about Impala LDAP authentication at:
