Chapter 11. Using Existing Databases

Ambari installs the PostgreSQL, MySQL, and Derby databases for use with Ambari, Hive, Oozie, and Ranger respectively, as default options. You may instead use a new, or an existing, non-default database instance with these components. To prepare Ambari to connect to a database for Hive or Oozie, you must download and set up database connectors before you set up the Ambari Server by running ambari-server setup.

[Important]Important

Using the Microsoft SQL Server or SQL Anywhere database options are not supported.

Using MySQL requires the default, InnoDB engine for MySQL 5.6.
