Configure the Cluster to Use an External RDS as the Hive Metastore Database

If you want to use a relational database on the cloud platform as the Hive metastore database for the cluster, you must set cluster configuration properties in the Software Setting property of the Create Cluster task.

Configure the Create Cluster task to set configuration properties in the hive-site.xml configuration file on the cluster. Use a text file to specify hive-site settings, and specify the path to the file in the Software Settings property.

The following text shows sample configuration of the Software Settings property:

{
      "Classification":"hive-site",
      "Properties":{
         "javax.jdo.option.ConnectionURL":"jdbc:mysql:\/\/<RDS_HOST>:<PORT>\/<USER_SCHEMA>?createDatabaseIfNotExist=true",
         "javax.jdo.option.ConnectionDriverName":"<JDBC driver name>",
         "javax.jdo.option.ConnectionUserName":"<USER>",
         "javax.jdo.option.ConnectionPassword":"<USER>"
      }
   }

Example:

Example:
{
      "Classification":"hive-site",
      "Properties":{
         "javax.jdo.option.ConnectionURL":"jdbc:mysql:\/\/<host name>:<port number>\/hive?createDatabaseIfNotExist=true",
         "javax.jdo.option.ConnectionDriverName":"org.mariadb.jdbc.Driver",
         "javax.jdo.option.ConnectionUserName":"hive",
         "javax.jdo.option.ConnectionPassword":"hive"
      }
   }

hive-site

javax.jdo.option.ConnectionURL: JDBC connection string for the data store.
javax.jdo.option.ConnectionDriverName: JDBC driver class name for the data store. Specify a JDBC driver that is compatible with the cloud platform.
javax.jdo.option.ConnectionUserName: User name to use to connect to the database.
