Nigel Daley commented on HADOOP-2122:
-------------------------------------
+1 to this Jira. It would be good to include these attributes as well for each
parameter:
* the legal values
* the default value if it's unset
* the behaviour if the value is illegal (is the default taken or an exception
thrown or ?)
> Document config parameters for each Map-Reduce class/interface

> Key: HADOOP-2122
> URL: https://issues.apache.org/jira/browse/HADOOP-2122
> Project: Hadoop
> Issue Type: Improvement
> Components: documentation
> Reporter: Arun C Murthy

> 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?
