Setup a secure server connection

Complete the following steps to set up a secure connection from the AEL daemon to the cluster:

1. Create a keytab and server principal to use for your server access.

2. Navigate to the adaptive-execution/config/application.properties file and open it with a text editor. Set the values for your environment as in the following table:

   Parameter	Value
   keytabLocation	Path to the keytab used for the Kerberos principal.
   kerberosPrincipal	Path to the Kerberos service principal that has the authority to impersonate another user.
   disableProxyUser	The AEL daemon can impersonate a proxy user when authenticating to your secure cluster. Set to true to disable the proxy user. The acting user will then be the Kerberos service principal. The default value is false.

You can now test your AEL configuration by creating a run configuration using the Spark engine. See Run configurtaions in the Pentaho Data Integration document for instructions.
