Not sure I follow. :(
Coprocessor is not MapReduce. MapReduce already takes care to run your code local to the data.
Coprocessors can be seen like lightweight Map-only MapReduce job.

It sounds to me that this is not what you want and that you need to have access to some sort of resources only available on one specific server? Because if that is not the case, then you are simply using the coprocessors the wrong way IMHO.
