Subject issue regarding shuffle process in hadoop mapreduce
Date Sun, 25 Apr 2010 07:23:45 GMT
Hey All,
           Can anyone tell me that how does the shuffle process that happens
after the mapping task takes place. Is it the responsibility of mappers to
push data to the reducers or is it the responsibility of task trackers to
shuffle the data to the reducers. And which communication protocol does
shuffle process use to shuffle.

Regards,
Ahmad Shahzad
