Subject Partition fetching by a reducer
Date Fri, 29 Oct 2010 05:00:21 GMT
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..
