Excuse me, I added the -Xmx option and restarted the hadoop services using sbin/stop-all.sh && sbin/start-all.sh
however still I get heap size error. How can I find the correct and needed heap size?

My question is, that option should be passed to java command and not Mahout. As result, running "./bin/mahout -Xmx 2048M" shows that there is no such option. What should I do? Regards, Mahmood
