+Alluxio Catalog Service
+^^^^^^^^^^^^^^^^^^^^^^^
+
+In addition to using Alluxio storage system in a Hive metastore, the Hive connector
+can also connect to an Alluxio Catalog Service. <https://docs.alluxio.io/ee/user/stable/en/core-services/Catalog.html?utm_source=prestodb&utm_medium=prestodocs>
+Alluxio catalog service is a caching metastore that can cache the information from different underlying metastores.
+It currently supports Hive metastore as an underlying metastore.
+To configure the Hive connector for Alluxio Catalog Service, create a catalog properties file
+such as ``/etc/catalog/catalog_alluxio.properties`` and include the following:
+
+.. code-block:: none
+
+ connector.name=hive-hadoop2
+ hive.metastore=alluxio
+ hive.metastore.alluxio.master.address=HOSTNAME:PORT
