Using an existing or installing a default database

Ambari installs a default database for each component. You may choose to set up components with a new or existing, non-default database.

Ambari installs the PostgreSQL, MySQL, and Derby databases for use with Ambari, Hive, and Oozie 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 non-default database, you must download and set up database connectors before you set up the Ambari Server by running ambari-server setup.

	Important
	Using Microsoft SQL Server or SQL Anywhere database options are not supported. Using MySQL requires the default, InnoDB engine for MySQL 5.6.
