Subject Joining N DataSets????
Date Fri, 26 Jul 2013 19:11:34 GMT
Hi
I am working on a problem where I need to join multiple datasets. The
problem is explained below.

Given   N number of datasets, having M relations in between them, i want to
merge them into one dataset where relations could be 1-many or 1-1 and for
connectivity, it is essential that  we have atleast N-1 relations so M >=
N-1


Kindly let me know how to solve this issue using Map Reduce

Thanks in advance
