Probably by that Shahab means that you can use NullWritable as your key
from the Reducer. If you do so your Reducer will just emit the value
without the key. Something like this :
output.collect(NullWritable.get(), new MyWritable(text));

If I understood your issue correctly, you want to only output the 'value'
part from the reduce after your job ends. Right?
If that is the case then you can do something like that in the reduce
function.
This will only output value and no key part.
*output.colllect(NullWritable.get(), value);*
(
Sorry, I think I didnt understand,
Does NullWritable go to replate MyWritable? But this is may value. My key
is a Text.
