The Catalog Service is an application service that runs Enterprise Data Catalog in the Informatica domain. The Catalog Service manages the connections between service components and the users that have access to Enterprise Data Catalog search interface and Catalog Administrator.
The catalog represents an indexed inventory of all the configured data assets in an enterprise. You can find metadata and statistical information, such as profile statistics, data asset ratings, data domains, and data relationships, in the catalog.
Ensure that you import the Hadoop cluster certificates to the domain trust store before you create a Catalog Service for a Hadoop cluster that uses SSL protocol.
