ou elaborate on how you reached the conclusion that the output
of some maps isn't going through the combiner?
Also, what version of hadoop are you using? hadoop-0.18 onwards
there
aren't guarantees on the number of times a combiner is run...

data,
some of the mapper output is directly reached reducer. I am wondering how
can this be possible when I have specified combiner in the job
configuration. Can any one please let me know if this thing happens?
