Bertrand/Mohamed, You guys are awesome!!!!. Thanks a million… Commenting out the Combiner class in the driver solved the issue.
p.s. I have one more small dilemma. I am trying to create xml from two files. The input for my 3rd MR job is the (Text,Text) output from two MapReds. I feed my inputto MR3 as KeyValueTextInputFormat and whenever try to simply output out.collection(key,key). The keys are there. My keys are single value Text() but the values is multi-line xml Text(). Can you put me in the right direction on how I can properly bring in these values to combine into a larger XML. For now the output of the 3rd MR job is a mess of values with the keys trailering somewhere at the bottom.

Please do a real test with a specified input. We can only guess. Bertrand On Tue, Oct 2, 2012 at 6:52 PM, Chris Nauroth <[email protected]<mailto:[email protected]>> wrote: Is there also a Mapper? Is there any chance that logic in the Mapper wrapped the values with the tags too, so that the records were already wrapped when they entered the reducer logic?
