Configuring a Ranger or Ranger KMS Database: MySQL/MariaDB
Prior to upgrading your cluster to CDP Private Cloud Base you must configure the MySQL or MariaDB database instance for Ranger by creating a Ranger database and user. Before you begin the transition, review the support policies of database and admin policy support for transactions.
A supported version of MySQL or MariaDB must be running and available to be used by Ranger. See Database Requirements.
When using MySQL or MariaDB, the storage engine used for the Ranger admin policy store tables must support transactions. InnoDB supports transactions. A storage engine that does not support transactions is not suitable as a policy store.
