Adding a Catalog#
In Presto, connectors allow you to access different data sources – e.g., Hive, PostgreSQL, or MySQL.
To add a catalog for the Hive connector:
Create a file
~/.prestoadmin/catalogwith the following content:
Distribute the configuration file to all of the nodes in the cluster:
./presto-admin catalog add hive
./presto-admin server restart
You may need to add additional properties for the Hive connector to work properly, such as if your Hadoop cluster is set up for high availability. For these and other properties, see the Hive connector documentation.
