> fix mapreduce.task.io.sort.factor=1 lead to an infinite loop.

>             Project: Hadoop Map/Reduce
>          Issue Type: Bug

> *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").
