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
but when i try to read it using IFile.Reader it reads all data not single
key value pair
*IFile.Reader reader = new* IFile.Reader<KEYIN,
VALUEIN>(context.getConfiguration(), localFs, file, *null*, myReadCounter);
DataInputBuffer keyRead = new DataInputBuffer();
DataInputBuffer valueRead = new DataInputBuffer();
when i say keyRead.getData()
it print all key value pair in that buffer i want single key value pair.
