GridMix benchmark 配置，到底该做何解？

 streamSort.smallJobs.numOfJobs
 10,5



 streamSort.smallJobs.numOfReduces
 6,3

《Hadoop Operations and Cluster Management Cookbook》中对于对于上面 benchmark 配置的参数说明是：These two properties specify that we will use 10 small stream sort jobs with 6 reducers, and 5 small stream sort jobs with 3 reducers.

github 上对示例中的说明是：

  javaSort.smallJobs.numOfJobs
  8,2
  



  javaSort.smallJobs.numOfReduces
  15,70
  

The above spec means that we will have 8 small java sort jobs with 15 reducers and 2 small java sort jobs with 17 reducers.（这是把 70 写成了 17 吗？）

晕了。
