Uninstalling RPM Deployments

This topic describes how to uninstall Cloudera Data Science Workbench from a cluster.

RPM Deployments

  1. Run the following command on the master host to stop Cloudera Data Science Workbench.
    cdsw stop
  2. (Strongly Recommended) On the master host, backup the contents of the /var/lib/cdsw directory. This is the directory that stores all your application data.

    To create the backup, run the following command on the master host:

    tar cvzf cdsw.tar.gz /var/lib/cdsw/*
  3. To uninstall Cloudera Data Science Workbench, run the following commands on the master host and all the worker hosts.
    cdsw stop
    yum remove cloudera-data-science-workbench
  4. Remove all your user data that is stored in /var/lib/cdsw on the master host from the deployment. This step will permanently remove all user data.
    sudo rm -Rf /var/lib/cdsw
