Subject Generic Performance Tuning of MapReduce
Date Mon, 15 Nov 2010 19:37:19 GMT
I have been looking around on some configuration parameters to improve the
performance of MapReduce.

Basically, I'm looking at the mapred-site.xml and so far I have set the
following values:

mapred.tasktracker.map.tasks.maximum = 40
mapred.tasktracker.reduce.tasks.maximum = 8
mapred.child.java.opts = -Xmx300m

Are there any generic values that I can placed inside the mapred-site.xml to
improve the overall performance of MapReduce.
