How to speed up of Map/Reduce job?
----------------------------------

                 Key: HADOOP-7128
                 URL: https://issues.apache.org/jira/browse/HADOOP-7128
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Igor Babkin
            Priority: Critical


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?
