Upgrading a CDSW 1.9.1 Deployment from HDP 2 to HDP 3

Cloudera Data Science Workbench ships a single RPM that can be used to install CDSW on both, HDP 2, and HDP 3 clusters.

The upgrade path for RPM deployments is:
  1. Upgrade from HDP 2.6.5 (or higher) to HDP 3.1.x (or higher).
  2. Restart Cloudera Data Science Workbench. Check Ambari to ensure that there are no more stale configs on the cluster hosts.
