> 1. Can you include the same improvement to new api
org.apache.hadoop.mapreduce.lib.output.MultipleOutputs as well.
>
> 2. Can you add a test case if possible, else pls provide a reason.
Thanks @PrabhuJoseph for review and suggestions.
1. I have updated the
```org.apache.hadoop.mapreduce.lib.output.MultipleOutputs``` as well.
2. I think we dont need a specific unit test in this case as we just
paralleling the current calls and current unit tests are already testing the
over features/cases
