  • Cluster scheduling #

    Cluster scheduling ensures that your clusters do not suspend automatically when idle. Stopped clusters must be started manually, and are therefore not impacted by any defined scheduling. Your cluster must be in running or suspended status to be affected by scheduling.

    The following sections describe how to create schedules for your clusters.

    Create a cluster schedule #

    In the Provide name and description of schedule section, provide the following details:

    • Name: Provide a name for your schedule.
    • Description: Add an optional description for your schedule.

    Select time zone #

    • Time zone: Choose a time zone. The time zone is set to the time zone of the user, by default.

    Specify timeframe #

    Timeframes override configured idle shutdown times to keep your cluster running. Idle shutdown occurs once the scheduled stop time is reached and the cluster is inactive. Idle shutdown transitions the cluster into suspended status.

    For example, a cluster with an idle shutdown time set to 5 minutes is scheduled to run from 9:00 AM to 10:00 AM. If the cluster is inactive from 9:55 AM to 10:00 AM, it automatically suspends at the scheduled stop time. If the cluster is still in use until 10:03 AM, it automatically suspends at 10:08 AM.

    To specify a timeframe:

    • Select days: Choose one or more days.
    • Set times: Expand the menus in the Start time and Stop time fields, and choose start and stop times. You can also input the times you want your cluster to run. Time intervals are available in 15 minute intervals, starting at the top of the hour and progressing by a quarter of an hour. For example, 9:00 AM, 9:15 AM, 9:30 AM, 9:45 AM, 10:00 AM. To reset Start time and Stop time fields, click Clear.
    • Add more times: Click to add an additional time interval for the timeframe. You can create as many time intervals as required. To remove a time interval, click Remove.
    • Add another timeframe: Click to add an additional timeframe, and follow the preceding steps. You can create as many timeframes as required. To remove a timeframe, Click Remove timeframe.

    Choose cluster(s) to use schedule #

    This optional step allows you to assign a schedule to one or multiple clusters:

    1. Expand the Clusters field, and select one or more clusters to assign the schedule to.
    2. Click Create schedule to create and view your schedule. Newly created schedules are enabled, by default.
