Subject Duplicating map reduce tasks
Date Wed, 02 Jul 2014 06:00:59 GMT
Hi,
I would like to provide the map reduce jobs in the following format :-

<Map Reduce task> <number_of_replicas>

I want to execute the specified task the specified number of
times(number_of_replicas) on different nodes and then I want to compare the
results produced by these task copies. Is it possible to do this in Hadoop
Map reduce? If not possible, is there any means by which I can modify the
code of map reduce so that I can do it?

Thanks & Regards,
Tina
