You can prefix the runtime arguments with a ``<scope>.`` to achieve this.\n+Currently supported scopes are ``dataset``, ``mapreduce``, and ``spark``.\n+\n+Example: To set the runtime argument ``read.timeout=30`` for MapReduce program ``oneMapReduce`` in the Workflow,\n+argument can be provided with the scope as ``mapreduce.oneMapReduce.read.timeout=30``. In this case ``oneMapReduce``\n+will receive two arguments - one with the scope ``mapreduce.oneMapReduce.read.timeout=30``\n+and another with the scope removed ``read.timeout=30``. However other programs and datasets used in the\n+Workflow will receive only one argument ``mapreduce.oneMapReduce.read.timeout=30``.\n+\n+An argument can also be prefixed with ``<scope>.*`` to apply it to all programs or datasets in the Workflow as\n+represented by the Scope.\n+\n+Example: If the runtime argument is specified as ``mapreduce.*.read.timeout=30``, all MapReduce programs\n+in the Workflow will receive two arguments - one with the scope ``mapreduce.*.read.timeout=30`` and another\n+with the scope extracted ``read.timeout=30``.
