CompositeInputOutputContext

This context either writes to the hadoop context or to an output channel depending on the value tag

If the result of the map operation must go to the reducer, use the normal hadoop context if it must go to an output file directly (i.e. to a "bypass" output tag), use the corresponding output channel as a reducer
