David Ciemiewicz commented on HADOOP-2122:
------------------------------------------
Did this ever get documented?
Is there a pointer to where these config params are documented?
It seems like this would have been addressed after 2 years but I can't find any
such table for options such as fs.inmemory.size.mb
> Document config parameters for each Map-Reduce class/interface

> 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?
