Subject Re: reuse of MultipleOutputFormat with new API
Date Thu, 22 Oct 2009 19:27:18 GMT
With new api, functionality of MultipleOutputFormat and MultipleOutputs 
is combined into one as 
org.apache.hadoop.mapreduce.lib.output.MultipleOutputs in branch 0.21.
You can use the same.

Thanks
Amareshwari
