>                 Key: MAPREDUCE-7
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7
>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>            Reporter: Amar Kamat
>
> I printed the progress in the {{Progress.java}} for every progress made and I found this scenario
> {noformat}
> update called for reduce with progress 0.99998355
> update called for reduce with progress 0.99998355
> update called for reduce with progress 1.0000043
> update called for reduce with progress 1.0000043
> update called for reduce with progress 1.0000244
> {noformat}
> Following are the lines I added to get this 
> {code:title=Progress.java|borderStyle=solid}
> /** Called during execution on a leaf node to set its progress. */
>   public synchronized void set(float progress) {
>     System.out.println("update called for " + status + " with progress " + progress);
>     this.progress = progress;
>   }
> {code}
> This needs investigation and will also explain why occasionally users see jobs that are complete and their progress less that 100%.
