hi, thanks for reply I am investigating what is and how "thin virtualization" works
Do you know if HADOOP is indicated to work under "thin" environment ? On Hadoop I will put large workloads and this thin virtualization utilizes more resources than exists (shareable environment) that is, if I have a real physical necessity of 500gb for each hadoop host and my Thin Virtualization has 2TB on NFS, I can have only 4 virtual machines (500GB each), or less. For this case I believe clone virtual machine is the right choice. But in my environment it takes 1h30m to build one cloned virtual machine. Am I correct ?
