Perform the following steps to specify the
credentials for your Knox security, which is only available for the Hortonworks
driver.
After you specify your security credentials, PDI tests the
connection to your Hadoop cluster. If no errors occur during the connection, PDI is successfully
connected to your Hadoop cluster.
If you have problems, see the troubleshooting section in the Administer Pentaho Data Integration and Analytics document to resolve the errors, then test your connection again.
