Uninstalling Unravel bits from on-prem platforms

To uninstall Unravel from on-prem platforms, you must roll back the Unravel-specific changes made in your cluster manager. This requires a restart of the affected services. Hence, to avoid an impact on the user's application, it is recommended to do this during a maintenance window.

  1. Rollback the changes made to Ambari/Cloudera. Refer to CDH additional instrumentation and HDP additional instrumentation to check the corresponding changes.

  2. Restart the affected services.

  3. For Ambari, remove Unravel's sensor jars from each node in the cluster.

    rm -rf /usr/local/unravel-agent
    rm -rf /usr/local/unravel_client


    Ensure to remove the sensor jars only after rolling back changes in Ambari.
