Jian Zhang updated MAPREDUCE-7402: ---------------------------------- Description: *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! *How to reproduce:* This bug can easily occur by setting configuration.set("mapreduce.task.io.sort.factor", "1"). was: *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.
