            System library path to use for workflow applications.
            This path is added to workflow application if their job properties sets
            the property 'oozie.use.system.libpath' to true.

        <description>
            If set to true, submissions of MapReduce and Pig jobs will include
            automatically the system library path, thus not requiring users to
            specify where the Pig JAR files are. Instead, the ones from the system
            library path are used.
