> I have a problem. I installed Hadoop on 2-nodes cluster and run Wordcount example. It takes about 20 sec for processing of 1,5MB text file. We want to use Map/Reduce in real time (interactive: by user's requests). User can't wait for his request 20 sec. This is too long. Is it possible to reduce time of Map/Reduce job? Or may be I misunderstand something?
