You can create the Enterprise Data Lake Service and the Data Preparation Service during the installation process. If you want the installer to create the services, it creates both services on a node. The installer prompts for connection objects associated with the Hadoop environment.

To create the services, the domain must be integrated with the Hadoop environment before you run the installer. For more information about integrating the domain with the Hadoop environment, see the

Informatica 10.2.1 Big Data Management Hadoop Integration Guide

.

Informatica recommends that you associate dedicated Model Repository Service and Data Integration Service instances with the Enterprise Data Lake Service. You can create a Model Repository Service and Data Integration Service to associate with the Enterprise Data Lake Service during installation, or you can associate existing services with the Enterprise Data Lake Service.

If you create a Model Repository Service, you must specify the details for the Model repository database used by the Model Repository Service.
