Hi,
In my company we sometimes uses KVM to launch test or small demo clusters. Every developer also has a KVM pseudo distributed cluster on its computer. Nonetheless, I would not recommend using KVM for production clusters. Check this link about all the theory of Hadoop with virtualization: http://wiki.apache.org/hadoop/Virtual%20Hadoop Regards, Sourygna Luangsay From: ch huang [mailto:justlo...@gmail.com] Sent: jueves, 08 de agosto de 2013 7:31 To: user@hadoop.apache.org Subject: is it ok? build hadoop cluster on kvm on product envionment? hi,all: my company has not much burget for boxes,if i build cluster on kvm ,it will cause a lot of impact on performance??
