    When I try to call Sandbox from my Java program from within Eclipse, I get:
    ERROR security.UserGroupInformation: PriviledgedActionException as: …. cause:java.net.UnknownHostException: unknown host: sandbox
    java.net.UnknownHostException: unknown host: sandbox

    Hi Wadwood,

    From where you are running Eclipse have you ensured you can resolve the sandbox hostname?
    You may need to add it into the hosts file as 127.0.0.1 IP (or whichever IP it is assigned)

    Thanks

    Dave
