> 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?
