Creating an External Database Configuration
You can deploy each Hadoop cluster with its own external database for all Hadoop distributions (Cloudera, MapR, and Hortonworks) using instant Hadoop cluster and customized Hadoop cluster creation actions.
You can configure a new database or use an existing database in Cisco UCS Director Express for Big Data. The Oozie, Hive, and Hue services use configured database information that you have created using the Create External Database Configurations dialog.
Note |
MySQL is the only supported external database in Cisco UCS Director Express for Big Data. |
