    I am using the gsInstaller to deploy a single node cluster on a Cent OS 6.3 Virtual Machine using VMWare Player.

    On Step 7 of the tutorial, I receive the following error/failures when running the gsInstaller.sh script as per the log file:

    ==============================================================================

    Do you have JDK installed on your system?
    Why you use gsInstaller?
    HMC is a way to go, please, use it instead.

    Yes, I have the JDK installed. Less is hidden behind the UI and I was told it is convenient for a single cluster install.

    Based on the error message, your JDK is not functioning.
    And what do you mean by ” Less is hidden behind the UI” and who told you such things?
