Tests performed on a single calxeda SOC with ubuntu 12.10

Prerequisites

  • Install Java/JRE
  apt-get update
  apt-get install default-jre
  • Setup passwordless ssh for user/root (I used root in this example, separate hadoop user should really be setup!)
  ssh-keygen -t rsa
  # dont enter a passphrase, just hit enter twice for a blank passphrase
  cd .ssh
  cat id_rsa.pub >> authorized_keys
  chmod 600 authorized_keys
