Subject Mappers only job, output sorted?
Date Sat, 24 Mar 2012 17:30:40 GMT
i have mappers only job - number of reducers set to 0. Its hadoop 0.22 
and output from job is this:

2012-03-24 18:24:22,117 WARN org.apache.hadoop.util.NativeCodeLoader:

is this job still sorting keys in mapper output? Because task status for 
mapper says "map > sort". I do not need output sorted.
