Hello, In my application I need to reduce the original reducer output keys further.
I was reading about Chainreducer and Chainmappers but looks like it is for : one or more mapper -> reducer -> 0 or more mappers I need something like: one or more mapper -> reducer -> reducer Please help me figure out the best way to achieve it. Currently, the only options seems like I write another map reduce application and run it separately after the first map-reduce application. In this second application, the mapper will be dummy and won't do anything. The reducer will further club the first run outputs. Any other comments such as this is not a good programming practice are welcome, so that I know I am in the wrong direction.. -- View this message in context: http://www.nabble.com/Can-I-have-multiple-reducers--tp26018722p26018722.html Sent from the Hadoop core-user mailing list archive at Nabble.com.
