Automatic Downloads of Framework Updates

Describes how to automatically upgrade tools and frameworks included with the HPE Ezmeral Unified Analytics Software installation.

Prerequisites:
  • Sign in to HPE Ezmeral Unified Analytics Software as Administrator.

You can simultaneously upgrade frameworks by enabling automatic downloads of updates when new versions are available. If frameworks have updates available for a new version, every hour HPE Ezmeral Unified Analytics Software bundles those updates and displays the update bundle on the Available Updates table as Tools & Frameworks.

To upgrade frameworks by enabling automatic downloads, follow these steps:
  1. In the left navigation bar, click Administration → Settings.
  2. Click Updates → Download Updates.
  3. To enable the automatic download of framework updates, toggle Automatic downloads of updates to Enabled.
    NOTE
    To disable automatic download of framework updates, toggle Automatic downloads of updates to Disabled.


  4. Once you see the Tools & Frameworks update bundle in the Available Updates table, click the bundle to view details. In the Details dialog box, you can see the name, description, the current version of the framework and chart, and the new available version for the framework and chart. Once you see the new available versions for the update, you can perform the following actions by clicking on the Actions menu.
    To batch update frameworks immediately, follow these steps:
    1. Click Update in the Actions menu. This will open an Update Now dialog box and you can compare the current and new available versions of frameworks for upgrade.
    2. Click Update Now to immediately start framework updates. Wait for framework updates to be in the In Progress status.
      NOTE
      You cannot cancel framework updates once it is in the In Progress status.

    Result: You can navigate to the Tools & Frameworks screen to see frameworks are now in the Upgrading status.

    To schedule batch framework updates for later, follow these steps:
    1. Click Schedule in the Actions menu. This will open a Schedule Update dialog box and you can compare the current and new available versions of frameworks for upgrade.
    2. Select a date and time to schedule the update. Wait for framework updates to be in the Scheduled status.
    3. Once the framework updates are in the Scheduled status, you can perform the following actions from the Actions menu.
      Cancel

      You can cancel the scheduled updates any time before update starts or if updates are not in the In Progress status yet.

      Reschedule

      You can reschedule the scheduled updates any time before update starts or if updates are not in the In Progress status yet.

      Update

      You can update frameworks immediately even though it has been scheduled for a later date and time.

  5. Once your updates are complete, the Tools & Frameworks update details will be displayed in the Update History table. You can click Tools & Frameworks to view details. In the Details dialog box, you can see the name, description, the current version of the framework and chart, and the new available version for the framework and chart.

Failure and Rollback

When you are upgrading frameworks, if one of the framework updates fails, the application tile for that framework will be in the Error status and the failed application will be rollbacked to the previous version from which you were upgrading to the new version.

For example: In HPE Ezmeral Unified Analytics Software, if you upgraded ten frameworks and nine frameworks are upgraded and in the Ready status, and if one farmework upgrade failed and is in the Error status with a warning message on the framework tile, then only that failed application is rolled back to the previous version whereas nine frameworks are successfully upgraded to new versions.

If for some reason the rollback fails and the framework is in the error state, you must contact HPE support to resolve this issue.
