Microsoft Power BI desktop is free and is able to successfully connect to a Cloudera Impala or hive database with Kerberos security enabled. The below blog only shows Impala driver but you can use same procedure with Hive driver also.
The basic steps are:
- Install the MIT Kerberos client for Windows and make sure you have successfully got a ticket to the Cloudera CDH cluster.
- Install the Power BI desktop
- Create a ODBC System DSN. I used the MicroStrategy Impala ODBC driver client version 1.02.09.1013 (created by Simba Technologies).
- While creating the ODBC DSN use the following parameters:
- Host=Impala datanode hostname, Port=21050, Database=default, Authentication Mechanism=Kerberos, Realm=Your kerberos realm, Host FQDN=_HOST, Service Name=impala. Leave the Delegate Kerberos Credentials and Use Keytab as blank. Transport Buffer size=1000, Delegation UID leave blank.
- Test the connect if successful otherwise it wont work. Make sure you got a new kerberos ticket in the MIT Kerberos client using your userid and password.
- After ODBC Test is successful then go to the Power BI desktop and click on Get Data.
- Select More->Other->ODBC option->connect. It will show a dropdown for your recently created ODBC DSN for Impala with whatever name you specified.
- Press OK and you should be able to see your database and tables in Cloudera Impala CDH cluster and do any visualization in PowerBI.
