[jira] Created: (HADOOP-7128) How to speed up of Map/Reduce job?
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?
