Subject Re: multicore node clusters
Date Thu, 10 Sep 2009 02:36:58 GMT
> I've a cluster where every node is a multicore. From doing internet searches I've figured
out that I definitely need to change mapred.tasktracker.tasks.maximum according to the number
of clusters. But there are definitely other things that I would like to change for example
mapred.map.tasks. Can someone point me out the list of things I should change to get the best
performance out of my cluster ?

nothing will give you better results than benchmarking with some jobs
indicative to your domain!
