8. Upgrade Slider

During the upgrade process, existing Slider applications will continue to use the older version of the libraries.

To upgrade Slider so that new applications will use the newer version of Slider:

  1. Switch to the new Slider software:

    hdp-select set slider-client

  2. Use the Slider version command to verify that Slider was upgraded properly:

    ./slider version

New application instances can be launched with the new version while older instances are running.

We recommend that you retain the older version of Slider, to ensure compatibility between client and Slider App Master for applications that are created and started using the older version.

If the upgrade process fails, follow the steps in Downgrading the Cluster, starting with "Downgrade Slider." Otherwise, continue with the upgrade process.
