Test a cluster connection

Perform the following steps to test a cluster connection:

1. In the PDI client, select the View tab and navigate to the Hadoop clusters folder.

2. If needed, expand the Hadoop clusters folder then right-click the cluster you want to test and select Test cluster.

   The Test results dialog box appears.

   

   Test results dialog box

   For each tested connection, the dialog box displays one of the following icons to indicate the results:

   • A green checkmark indicates the connection to the cluster service was successful.

   • A yellow caution symbol indicates the cluster service information was not supplied, so the test for that component was skipped.

   • A red circle-backslash indicates the connection failed. Check the connection information and then test the connection again. If you suspect a different issue, see the troubleshooting section in the Install Pentaho Data Integration and Analytics document or consult the cluster administrator.Note: You can click the drop-down arrow in the Hadoop file system test for more details.

3. Click Finish.

If no errors occur during the connection, PDI is successfully connected.

If you have errors, see troubleshooting section of the Administer Pentaho Data Integration and Analytics document to resolve the issues then test your connection again. When no error messages are returned, the connection is properly configured.
