Dear all,
This is a beginner to Hadoop. I am looking into how to use virtual machine in Hadoop, and I have some general questions about HOD. Can I consider HOD a virtual machine for running Hadoop jobs?(usually VMs are really big, but this one seems light-weighted.) Is the configuration of HOD over a physical cluster can only be done by the root user? (I tried as a common user, but I got stuck on configuring Torque) Is there any other virtual machines that I can use to provide a Hadoop cluster over a physical cluster? I am sorry for the elementary questions, but I am really uncertain about these. I really appreciate it if you care enough to clarify them for me. Thanks a lot! Boyu
