I am using multiple inputs to do user data integration from a variety of sources and there is meta-information that needs to be added to records from legacy systems that is common per input but not available in the record itself. How can I send parameters to a specific mapper using multiple inputs so that this information can be retreived during the setup phase of the mapper for all mappers of a given input?

You might want to consider using the Distributed Cache mechanism to distribute your metadata files out to the working directory of each map task and then just access it from your application code directly.
