Kerberos Account
In this article
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.
