Overview

Use this account type to connect Hadoop Snaps with data sources that use Kerberos accounts.

Prerequisites

None.

Limitations

...

The security model configured for the Groundplex (SIMPLE or KERBEROS authentication) must match the security model of the remote server. Due to limitations of the Hadoop library, we are only able to create the necessary internal credentials for the configuration of the Groundplex.

Known Issues

None.

Note


Even though when you pass both client and server principals here, the Snap only validates the client information and not the server information. This is because server validation requires information that is available only in the Snap's settings and not the Account settings.
