> Questions such as why is the no. of tasks 32 when the split count is set to
> 20 :
> set tez.am.grouping.by-count=true;
> set tez.am.grouping.split-count=20;
> Map 1: 16(+16)/32 Map 3: 1/1 Map 4: 1/1 Reducer 2: 0/1
> It would be good if there was a definite doc that users could be redirected
> to.
