Create the Interactive Data Preparation Service

Create the
Interactive Data Preparation Service

When you install

Enterprise Data Preparation

on a gateway node, you can create the

Interactive Data Preparation Service

and the

Enterprise Data Preparation

Service during installation.

If you do not create the

Enterprise Data Preparation

Service and the

Interactive Data Preparation Service

during installation, or if you install

Enterprise Data Preparation

on another node in the domain, you can use the Administrator tool to create the services after you install the

Enterprise Data Preparation

binaries.

Specify the name of the

Interactive Data Preparation Service

The name is not case sensitive and must be unique within the domain. It cannot exceed 128 characters or begin with @. It also cannot contain spaces or the following special characters: ` ~ % ^ * + = { } \ ; : ' " / ? . , < > | ! ( ) ] [

If you plan to use rules, you must associate a Model Repository Service and a Data Integration Service with the

Interactive Data Preparation Service

To skip associating a Model Repository Service and a Data Integration Service with the service, press

To associate a Model Repository Service and a Data Integration Service with the service, press

, and then enter the service names.

To create the

Interactive Data Preparation Service

during installation, enter the name of the current node.

If you do not want to create the service during installation, do not enter a value. You can use the Administrator tool to create the service after installation.

Choose whether to enable secure communication for the service.

To enable secure communication, press

To disable secure communication, press

If you enable secure communication for the service, select the SSL certificate to use.

To use the default Informatica SSL certificate contained in the default keystore and the default truststore, press

To use a custom SSL certificate contained in a custom keystore and truststore, press

, and then enter the path and file name for the keystore and truststore files. You must also enter the keystore and truststore passwords.

If you enable secure communication for the service, enter the port number for the HTTPS connection. If you enable non-secure communication for the service, enter the port number for the HTTP connection.

Select the Hadoop authentication mode.

To select the non-secure authentication mode, press

To select Kerberos authentication, press

If you select Kerberos, enter the authentication parameters.

The following table describes the authentication parameters that you must set if you select Kerberos:

Property	Description
HDFS Principal Name	Service Principal Name (SPN) for the data preparation Hadoop cluster.
Hadoop Impersonation User Name	User name to use in Hadoop impersonation as shown in the Impersonation User Name property for the Hadoop connection in the Administrator tool. If the Hadoop cluster uses Kerberos authentication, the Hadoop impersonation user must have read, write, and execute permissions on the HDFS storage location folder.
Kerberos Keytab File	Path and file name of the SPN keytab file for the user account to impersonate when connecting to the Hadoop cluster. The keytab file must be in a directory on the machine where the Interactive Data Preparation Service runs.

Specify the HDFS storage location, HDFS connection, local storage location, and Solr port number details.

The following table describes the properties you must set:

Property	Description
HDFS Storage Location	HDFS location for data preparation file storage. If the Hadoop cluster uses Kerberos authentication, the Hadoop impersonation user must have read, write, and execute permissions on the HDFS storage location folder.
HDFS Connection	HDFS connection for data preparation file storage.
Local Storage Location	Directory for data preparation file storage on the node where the Interactive Data Preparation Service runs. If the connection to the local storage fails, the service recovers data preparation files from the HDFS storage location.
Solr port	Solr port number for the Apache Solr server used to provide data preparation recommendations.
