Although not always required, it is recommended to install a Talend JobServer on the edge node of your Hadoop cluster. Then in the Preferences dialog box in Talend Studio or in Talend Administration Center if available to you to run your Jobs, define this Talend JobServer as the remote execution server of your Jobs.
