Pipeline Start Prerequisite

Before starting a pipeline that runs on a secured MapR cluster, you must log into the MapR node where Transformer is installed. This generates a ticket of a specified duration.

You can then start Transformer pipelines through the duration of the generated ticket.

Use the maprlogin command to log into MapR. The argument that you use depends on the authentication that you use:
  • Use the password argument for username-password authentication.
  • Use the kerberos argument for Kerberos authentication.

For more information about the maprlogin command, see the MapR documentation.
