Connect to Hive LLAP data from Power Query Desktop

To connect to an Apache Hive LLAP server:

  1. Select the Hive LLAP option from Get Data.

  2. Enter the URL to the Adobe Hive LLAP server. You can also enter an optional port number. Typically, the URL looks like http://[hostname]:[port number]. The components of the URL are:

    • The hostname (for example, hivellaphttp.southcentralus.contoso.com) is the hostname or IP address of the Apache Hive server.
    • The port number (for example, 10500) is the port number for the Apache Hive server. If the port number isn't specified, the default value is 10501 for the HTTP transport protocol and 10500 for the standard transport protocol.

    • Windows: Select this authentication type if you want to connect using Windows authentication.
    • Basic: Select this authentication type if you want to connect using Apache Hive LLAP authentication. Enter your Apache Hive LLAP User name and Password.

SSL Error in Power BI Service

After publishing a report in Power BI service, you need to update the credentials to the Hive data source in the cloud to refresh in Power BI service. After filling in the credentials, you might get the error:

Screenshot of Credential Error.

If you get this error and you see the following message in Fiddler trace, this is an SSL issue.

ODBC: ERROR [HY000] [Microsoft][ThriftExtension] (14) Unexpected response from server during a HTTP connection: Could not refill buffer

SSL is by default disabled when connecting directly from powerbi.com. To enable, you can use on-premises data gateway where you can enable encryption to connect and refresh reports from Power BI service. Enable HTTPS on Gateway
