mapreduce

My reducer class produces outputs with TextOutputFormat (the default OutputFormat given by Job). I like to consume this outputs after the MapReduce job complete to aggregate the outputs. In addition to this, I like to write out the aggregated information with TextInputFormat so that the output from this process can be consumed by the next iteration of MapReduce task. Can anyone give me an example on how to write & read with TextFormat? By the way, the reason why I am using TextFormat, rather Sequence, is the interoperability. The outputs should be consumed by any software.

In many real-life situations where you apply MapReduce, the final algorithms end up being several MapReduce steps. I.e. Map1 , Reduce1 , Map2 , Reduce2 , etc. So you have the output from the last reduce that is needed as the input for the next map. The intermediate data is something you (in general)… >>> More
