Rollback Cloudera Data Science Workbench to an Older Version
All stateful data for Cloudera Data Science Workbench is stored in the /var/lib/cdsw directory on the Master node. The contents of this directory are forward compatible, which is what allows for upgrades. However, they are not backward compatible. Therefore, to rollback Cloudera Data Science Workbench to a previous version, you must have a backup of the /var/lib/cdsw directory, taken prior to the last upgrade.
- Depending on your deployment, either uninstall the RPM or deactivate the current CDSW parcel in Cloudera Manager.
- On the master node, restore the backup copy you have of /var/lib/cdsw. Note that any changes made after this backup will be lost.
- Install a version of Cloudera Data Science Workbench that is equal to or greater than the version of the /var/lib/cdsw backup.
