ya i looked @ chain reducer but it will not help in my case Now i am able to write each key value pair received @ reducer(using IFile.Writer ) but when i try to read it using IFile.Reader it reads all data not single key value pair
Example: *IFile.Reader reader = new* IFile.Reader<KEYIN, VALUEIN>(context.getConfiguration(), localFs, file, *null*, myReadCounter); DataInputBuffer keyRead = new DataInputBuffer(); DataInputBuffer valueRead = new DataInputBuffer(); reader.next(keyRead, valueRead); when i say keyRead.getData() it print all key value pair in that buffer i want single key value pair.
