Before You Create the Enterprise Data Preparation Service

• •Verify that the Informatica domain has the following services which must be associated with the Enterprise Data Preparation Service:
• - Data Integration Service
• - Model Repository Service
• - Catalog Service
• - Content Management Service must be configured if you want to use the data domain discovery feature. Ensure that the database client is installed on all nodes of the Hadoop cluster with the correct settings in the hadoopEnv.properties file.
• - Interactive Data Preparation Service
Note: An Enterprise Data Preparation Service and a Interactive Data Preparation Service must have a one to one association. Do not associate one Enterprise Data Preparation Service with multiple Interactive Data Preparation Service instances, or one Interactive Data Preparation Service with multiple Enterprise Data Preparation Service instances.
• •If you use HTTPS to connect to the Enterprise Data Preparation Service, verify the location and password of the keystore and truststore files.
If the domain is secure, you must secure each Enterprise Data Preparation Service that you create in Enterprise Data Preparation. The Enterprise Data Preparation Service instances must use the same keystore and truststore files that the domain uses. If you use separate security certificates, you must add the security certificates for the Enterprise Data Preparation Service to the truststore and keystore file for the domain. You must use these keystore and truststore files for Enterprise Data Preparation. You must import the certificate file to the truststore location for the Interactive Data Preparation Service and Enterprise Data Preparation Service.
You must also use the same truststore files for the following services:
• - Data Integration Service
• - Model Repository Service
• - Catalog Service
• - Interactive Data Preparation Service
• - Enterprise Data Preparation Service

• •The following services in the domain and the YARN application must share the same common truststore file:
• - Data Integration Service
• - Catalog Service
• - Interactive Data Preparation Service
• - Enterprise Data Preparation Service
Note: You can use different keystore files for the Data Integration Service, Model Repository Service, and Catalog Service. If you use different keystore files, you must add certificates corresponding to each of the keystores into a common truststore file.
• •The Interactive Data Preparation Service and Enterprise Data Preparation Service must also share the same keystore file.
• •If you have configured Enterprise Data Preparation with one primary node and one or more backup nodes, you must copy the truststore files to a common directory and specify the same directory path for all nodes assigned to Enterprise Data Preparation.
