Connect to the Big Data Warehouse via Tableau - servinglynk/hslynk-open-source-docs GitHub Wiki

The critical thing you need to do when connecting to the HSLynk Big Data Warehouse via Tableau, is to make sure you have the correct driver installed.

We're on Cloudera version 5.10 and you can get the correct version of the drivers from Cloudera's website. You can choose Hive or Impala (they are competing protocols).

Driver for Hive. https://www.cloudera.com/downloads/connectors/hive/odbc/2-5-12.html

Driver for Impala. https://www.cloudera.com/downloads/connectors/impala/odbc/2-6-0.html

We've seen better performance when connecting to Impala.

After you've successfully installed the driver you need to select "Cloudera Hadoop" for the data source and it should take you to the screen below.

Once you select "Cloudera Hadoop" option you would get a screen like above where you can provide the type, authentication, transport, username and password.

You should be able to connect once you specify all the information above.

PS: We'll provide you the server, username and password via a secure channel.
