> fix mapreduce.task.io.sort.factor=1 lead to an infinite loop.
> -------------------------------------------------------------
>
> Key: MAPREDUCE-7402
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7402
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Jian Zhang
> Priority: Minor
> Labels: pull-request-available
> Attachments: screenshot-1.png
>
>
> *Describe：*
> In the method long computeBytesInMerges(int factor, int inMem), when
> factor is set to 1, and the initial numSegments>1, inMem=0, it will cause an
> infinite loop of while. Although setting factor to 1 is meaningless, and it
> will not be done in actual production, we need to remind users to avoid an
> infinite loop due to carelessness.
> !screenshot-1.png|width=600,height=400!
> *How to reproduce:*
> This bug can easily occur by setting
> configuration.set("mapreduce.task.io.sort.factor", "1").
