Hi ,
After the partitioning phase on each mapper output , on what basis is a partition assigned to a reducer ? Is this random or does hadoop employ some strategy ? Where can I find the portion of code doing this decision ? I tried Reducer / ReducerContext classes but couldn't find it. Also where can I find the reducer code which fetches the data that needs to be reduced by it .. Please give me some pointers.. Thanks Bharath.V 4th year undergraduate IIIT Hyderabad.
