Ravi Prakash commented on MAPREDUCE-3462:
-----------------------------------------
I'd be wary of adding it in src/main/..mapred-default.xml . I'd think
src/test/../mapred-test.xml is where it should be added if at all. If that
doesn't work currently, we should make it work. Just out of curiosity, do you
know of any other tests which are failing due to this exception?
