    Running a Cluster Inventory for a Big Data Account

    When you create a Big Data Account for an Hadoop cluster, a new system task (inventory collector) is created for each Big Data Account in the Big Data Tasks folder here: Administration > System > System Tasks. The system task collects the inventory of the Hadoop cluster for the selected Big Data Account and persists data in the Cisco UCS Director database. This collector adds to the system scheduler so that it can be called periodically as per the frequency configured in the collector (for example, 30 minutes).

    For more information on how to manage system tasks in Cisco UCS Director, see the latest Cisco UCS Director Administration Guide.
