Scheduler Administration

The Fuzzball scheduler is responsible for placing and managing jobs on compute nodes in your cluster. As a cluster administrator, you can monitor and manage scheduler behavior through various administrative commands.

Prerequisites

All scheduler administration operations require that a fuzzball admin context is set up and authorized like so:

$ fuzzball admin context create <context_name> <api_url>

$ fuzzball admin context login -u <admin_username> -p '<admin_password>'
