Amar Kamat commented on MAPREDUCE-2151:
---------------------------------------

I think Hong is referring to configuration parameters that are likely to modify 
the behaviour of the job and tasks (e.g _mapred.child._* , _mapreduce.job._* 
etc). Hong, is my understanding correct? Also *_-default.xml_ might not be 
available for reference comparison. Hence for now we might need to identify 
(i.e handpick) these configuration parameters and add them to _interesting 
properties_ list.
