Description

I propose we add a table in the javadoc for each user-facing Map-Reduce interface/class which lists, and provides details, of each and every config parameter which has any bearing on that interface/class. Clearly some parameters affect more than one place and they should be put in more than one table.

For e.g.
Mapper -> io.sort.mb, io.sort.factor
Reducer -> fs.inmemory.size.mb
...
etc.

It would very nice to explain how it interacts with the framework and rest of config params etc.

Thoughts?
