Creating an Informatica Cluster Service
You can choose to generate the Informatica Cluster Service when you install Enterprise Data Catalog or create the application service manually using Informatica Administrator.
If you plan to deploy Enterprise Data Catalog on multiple nodes, ensure that you configure Informatica Cluster Service and Catalog Service on separate nodes.
1. In the Administrator tool, select a domain, and click the Services and Nodes tab.
2. On the Actions menu, click New > Informatica Cluster Service.
The New Informatica Cluster Service: Step 1 of 4 dialog box appears.
3. Configure the general properties in the dialog box.
The following table describes the properties:
Property | Description |
|---|
Name | Name of the service. The name is not case-sensitive and must be unique within the domain. The name cannot exceed 128 characters or begin with @. The name cannot contain character spaces. The characters in the name must be compatible with the code page of the Model repository that you associate with the Catalog Service. The name cannot contain the following special characters: ` ~ % ^ * + = { } \ ; : ' " / ? . , < > | ! ( ) ] [ |
Description | Description of the service. The description cannot exceed 765 characters. |
Location | Domain in which the application service runs. |
License | License to assign to the Informatica Cluster Service. Select the license that you installed with Enterprise Data Catalog. |
Node | Node in the Informatica domain on which the Informatica Cluster Service runs. If you change the node, you must recycle the Informatica Cluster Service. |
Backup Nodes | If your license includes high availability, nodes on which the service can run if the primary node is unavailable. |
4. Click Next.
The New Informatica Cluster Service - Step 2 of 4 dialog box appears.
5. Configure the security properties in the dialog box.
The following table describes the properties:
Property | Description |
|---|
HTTP Port | A unique HTTP port number used for each Data Integration Service process. The defaults is 8085. |

HTTPS Port | Port number for the HTTPS connection. Required if you select Enable Transport layer Security. |
Keystore File | Path and file name of the keystore file. The keystore file contains the keys and certificates required if you use the SSL security protocol with Catalog Administrator. Required if you select Enable Transport layer Security. |
Keystore Password | Password for the keystore file. Required if you select Enable Transport Layer Security. |
SSL Protocol | Secure Sockets Layer protocol to use. |
6. Click Next.
The New Informatica Cluster Service - Step 3 of 4 dialog box appears.
7. Configure the Hadoop cluster properties in the dialog box.
The following table describes the properties:
Property | Description |
|---|
Hadoop Gateway Host | Host where Apache Ambari server runs. |
Hadoop Gateway Port | Web port for the Apache Ambari server. |
Gateway User | User name for the Apache Ambari server. |
Hadoop Nodes | Hosts where the Apache Ambari agents run. |
Override default password | Select this option if you want to change the default password for the cluster. Provide the new password in the Ambari Server Admin Password text box. |
Enable Kerberos Authentication | Select the option to enable Kerberos authentication for the cluster. |
KDC Type | Select one of the following Kerberos Key Distribution Center (KDC) types if you had selected the Enable Kerberos Authentication option: - - Active Directory. Select this option if you want to use Active Directory KDC.
- - MIT KDC. Select this option if you want to use MIT KDC.
Specify the following options after you select the KDC Type - - KDC Host. Name of the KDC host machine.
- - Administrator Server Host. The name of the administrator server machine that hosts the KDC server.
- - Realm. Name of the Kerberos realm on the machine that hosts the KDC server.
- - Administrator Principal. The Kerberos administrator principal.
- - Administrator Password. The Kerberos administrator password.
- - LDAP URL. This property applies to Microsoft Active Directory and represents the URL to the LDAP server directory.
- - Container DN. This property applies to Microsoft Active Directory and represents the Distinguished Name of the container to which the user belongs.
- - KDC Certificate Path. Path to the KDC certificate on the Informatica domain machine.

8. Click Next.
The New Informatica Cluster Service - Step 4 of 4 dialog box appears.
9. Configure the domain security options for Informatica Cluster Service.
The following table describes the properties:
Property | Description |
|---|
Domain is SSL Enabled | Specify if the Informatica domain is enabled for SSL. |
Domain Truststore File Location | Location to the domain truststore file. |
Domain Truststore Password | Password for the domain truststore file. |
Enable Service | Select the option to enable the Informatica Cluster Service immediately after you create the service. |
10. Click Finish.
Note: After you update the Informatica Cluster Service security options in Informatica Administrator, restart the Informatica Cluster Service.
Before enabling the Informatica Cluster Service in a Kerberos-enabled cluster, verify the following prerequisites:
- •You must configure the Key Distribution Center (KDC) hostname and IP address on all cluster nodes and domain machines in the /etc/hosts.
- •Make sure that the krb5.conf file is located in all cluster nodes and domain machines under the /etc directory.
- •For an SSL-enabled cluster or a Kerberos-enabled cluster, ensure that the domain truststore file is configured and copied to a common location accessible to all the cluster nodes.
- •If the Solr keystore and password are different from the keystore and password of Informatica Cluster Service, you must export the public certificate of Solr to all the cluster nodes and import the certificate to the YARN truststore and domain truststore.
