Changing the Credentials for the Data Integration Hub Hadoop Service

When you install

Data Integration Hub

, the installation assigns a user name and a user password for the user account of the

Data Integration Hub

Hadoop Service.

Perform the following steps if you change the credentials of the

Data Integration Hub

Hadoop Service at a later date.

Stop the

Data Integration Hub

services and close the Operation Console. For more information, see Starting and Stopping Data Integration Hub on Linux

Verify that the PowerCenter Integration Service is not running any

Data Integration Hub

workflows.

If you are changing a password, perform the following steps:

Run the password encryption utility and enter the new password in the following syntax:

<DIHInstallationDir>/dx-tools/dxpasswd.sh -p <NewPassword>

The password encryption utility encrypts the password and displays an encrypted string. For example,

-->ywo+o3cw8+O3iLdlhPprW2YA==
<--

Copy the encrypted string without the

--><--

indicators to the clipboard.

Open both copies of the

dx-configuration.properties

file in a text editor from the following locations on the machine where

Data Integration Hub

is installed:

<DIHInstallationDir>/DataIntegrationHub/tomcat/shared/classes/

<DIHInstallationDir>/conf/

If the

Data Integration Hub

Hadoop Service component is installed on a different machine than the machine where

Data Integration Hub

is installed, on the machine where the

Data Integration Hub

Hadoop Service is installed, open the

dx-configuration.properties

file in a text editor from the following location:

<DIHInstallationDir>/conf/

In all the copies of the

dx-configuration.properties

file, perform the following steps:

Search for the following text :

internal.service.username=
internal.service.password=

Replace the relevant value with the new value. If you are replacing a password, enter the encrypted string.

Save and close the files.

The content in all copies of the

dx-configuration.properties

file must be identical.

Start the

Data Integration Hub

Operation Console.

Verify that the PowerCenter Integration Service is running.

In the Navigator, click

Hub Management

Connections

The

Connections

page appears.

Click the

Test Connection

icon next to the DIH__STAGING__HADOOP connection.

Data Integration Hub

tests the connection. The process might take a few moments.

When the message "Connection successful" shows, click

in the

Test Connection

dialog box.

Start the

Data Integration Hub

Server services. For more information, see Starting and Stopping Data Integration Hub on Linux
