Logging into a Secure Cluster

The /opt/mapr/bin/maprlogin command line tool enables users to log into a secure MapR cluster. Users authenticate themselves to the cluster with a maprticket that can be generated in the following ways:

  • Run maprlogin password to authenticate with username and password.
  • Run maprlogin generateticket to request a service ticket for use by an external application or user account (based on the current user's ticket).
  • Run maprlogin kerberos after generating a Kerberos ticket with the kinit command.

For more details about different ways to generate tickets, see Tickets and Certificates.
