Generating a MapR Ticket from a Kerberos Ticket

On clusters that use Kerberos for authentication, a MapR ticket is implicitly obtained for a user that runs a MapR command without first using the maprlogin utility.

If you want to use a Kerberos ticket to generate a maprticket, follow these steps:

  1. Obtain a Kerberos identity by running kinit or by another mechanism.
  2. Run maprlogin kerberos to indicate that you have an existing Kerberos ticket. You can also specify these options: [ -cluster ] The name of the cluster. [ -duration ] The ticket duration in seconds.
