The value is specific to the distribution and version of Hadoop. This tutorial
                    uses Hortonworks 2.4 V3, which is 2.4.0.0-169. Your entry for this parameter
                    will be different if you do not use Hortonworks 2.4 V3. 
Information noteNote: When
                    running the code on the cluster, it is crucial to ensure that there is
                    unfettered access between the two systems. In this example, you have to ensure
                    that the Hortonworks cluster can communicate with your instance of 
Talend Studio. This is necessary because
                    Spark, even though it is running on the cluster, still needs to reference the
                    Spark drivers shipped with 
Talend. Moreover, if you deploy a
                    Spark Job into a production environment, it will be run from a 
Talend Job server (edge node).
                    You also need to ensure that there is unfettered communication between it and
                    the cluster.
