Subject How can I know how many mappers created?
Date Sun, 07 Aug 2011 06:45:20 GMT
Hi,
I just want 2 mappers created to do my job for there are only 2 data nodes.
I think that is the most efficient.
But how can I know how many mappers have been created while doing my job?
Can I do some sets to make it only 2 mappers created and each mapper runs on one node?
Thanks
