Subject Re: jobtracker heap
Date Thu, 17 Mar 2011 17:07:44 GMT
sure. my mistake. thanks.

I'm also trying to increase the reducer heap size (keeping the map with the
default 200m). I found 2 related properties:
1. mapreduce.reduce.java.opts
2. mapred.child.java.opts

Which should be configured and whats the purpose of the second property.

thanks,
Lior
