When designing a Job, set up the authentication configuration in the component you are using depending on how your MapR cluster is secured.
MapR supports the two following methods of authenticating a user and generating a MapR security ticket for this user: a username/password pair and Kerberos.
For further information about the MapR security mechanism, see MapR security architecture.
For a scenario about how to secure a MapR cluster, see Getting started with MapR security.
-
When your MapR cluster is secured with Kerberos only, you only need to set up the typical Hadoop Kerberos configuration for your Job in the Studio.
-
When your MapR cluster is secured with both the Kerberos mechanism and the MapR ticket security mechanism, you need to accordingly set up the configuration for both of them in your Job in the Studio.
For details about how to configure the MapR ticket security mechanism in the Studio, see Setting up the MapR ticket authentication.
-
When your MapR cluster is secured with the MapR ticket security mechanism only, proceed as explained in Setting up the MapR ticket authentication to set up the MapR authentication configuration for your Job in the Studio.
For an example of how to configure Kerberos authentication for a Talend Job, see How to use Kerberos in Talend Studio with Big Data.
Although this example uses Cloudera for demonstration, the operations it describes are generic and thus applicable to MapR as well.
