Hi all, I have a query regarding the functionality of combiner. Is it possible to ignore combiner code for some of the outputs of mapper and directly being sent to reducer though combiner is specified in job configuration? Because, I figured out that, when I am running on large amounts of 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?
