RE: Wonky reduce progress

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?
