Hi Marcos and Keith,

Thanks for bringing this to our attention. Saurabh is currently OOF, so I’ll 
pass this along to the EMR team.

Good call.  We can't use the conventional web-based JT due to corporate access 
issues, but I looked at the job_XXX.xml file directly, and sure enough, it set 
mapred.output.compress to true.  Now I just need to remember how that occurs.  
I simply ran the wordcount example straight off the command line, I didn't 
specify any overridden conf settings for the job.

Ultimately, the solution (or part of it) is to get away from .19 to a more 
up-to-date version of Hadoop.  I would prefer 2.0 over 1.0 in fact, but due to 
a remarkable lack of concise EC2/Hadoop documentation (and the fact that what 
docs I did find were very old and therefore conformed to .19 style Hadoop), I 
have fallen back on old versions of Hadoop for my initial tests.  In the long 
run, I will need to get a more modern version of Hadoop to successfully deploy 
on EC2.

Thanks.
