Please check the defect in MAPREDUCE jira
This is because the compression is enabled for map outputs and statistics
are taken on compressed data instead of original data.

Subject: Wonky reduce progress
I'm seeing really weird numbers in the JobTracker when monitoring jobs
launched by hives. Some jobs who above 100% completion while running
and others show less than 100% after the job completed. I tried
searching for JIRAs but didn't see any matches.
Has anyone else run into this?
