Using an External Database for Oozie, Hue, and Hive Metastore
Configuring an External Database for Oozie
By default, Cloudera Manager uses Derby for Oozie's database. If you want to use an external database for Oozie, you would do the configuration after Cloudera Manager is installed. For more information, see Using an External Database for Oozie in the Managing Clusters with Cloudera Manager.
Configuring an External Database for Hue
By default, Cloudera Manager uses SQLite for Hue's database. If necessary, you can configure Cloudera Manager to use an external database such as MySQL as the database for Hue - do this after Cloudera Manager is installed. For more information, see Using an External Database for Hue.
Configuring an External Database for Hive Metastore
By default, Cloudera Manager uses the embedded PostgreSQL database for the Hive metastore. If necessary, you can configure Cloudera Manager to use an external database such as MySQL or Oracle as the database for Hive metastore — do this before you install Cloudera Manager. For more information, see the instructions in Installing and Configuring an External PostgreSQL Database or in Installing and Configuring a MySQL Database .
