[jira] Created: (MAPREDUCE-2264) Job status exceeds 100% in some cases

Job status exceeds 100% in some cases 
--------------------------------------

                 Key: MAPREDUCE-2264
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2264
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobtracker
            Reporter: Adam Kramer


I'm looking now at my jobtracker's list of running reduce tasks. One of them is 120.05% complete, the other is 107.28% complete.

I understand that these numbers are estimates, but there is no case in which an estimate of 100% for a non-complete task is better than an estimate of 99.99%, nor is there any case in which an estimate greater than 100% is valid.

I suggest that whatever logic is computing these set 99.99% as a hard maximum.
