Advanced configurations in CDW Private Cloud
You can access advanced configurations in Cloudera Data Warehouse (CDW) Private Cloud from the left navigation pane on the CDW web interface. Some of these configurations must be enabled before you activate an environment and some can be applied by refreshing the environment, Database Catalog, and Virtual Warehouses.
