Hadoop authentication for Cloudera AI Workbenches

Cloudera AI does not assume that your Kerberos principal is always the same as your login information. Therefore, you will need to make sure Cloudera AI knows your Kerberos identity when you sign in.

This procedure is required if you want to run Spark workloads in an Cloudera AI Workbench. This is also required if connecting Cloudera Data Visualization running in Cloudera AI to an Impala instance using Kerberos for authentication.

Navigate to your Cloudera AI Workbench.
Go to the top-right dropdown menu, click Account settings > Hadoop Authentication.
To authenticate, either enter your password or click Upload Keytab to upload the keytab file directly.

Once successfully authenticated, Cloudera AI uses your stored credentials to ensure you are secure when running workloads.
