Follow these steps to install and configure MapR-DB.

Install MapR-DB

The MapR Sandbox is available as a virtual machine (VM) so the installation is straightforward.

The VM is configured to use a host-only network. Check that you have a host-only network configured in your environment.

Add the IP address of the VM to your /etc/hosts file. On Windows:
In the /etc/hosts file, use the MapR-DB machine name maprdemo.
The VM is a CentOS Linux. You can connect to it using SSH:
# password is mapr
ssh mapr@maprdemo

Set MAPR_HOME on Your Host

On your host Windows, Mac OSX, or Linux machine where you will write and run your Java applications, follow these steps:

  1. Create the following directory structure:
    /opt/mapr/conf  (for Linux and OSX)
    C:\opt\mapr\conf (for Windows)
  2. If you have a MapR client installed on your machine (existing /opt/mapr folder), use it; otherwise, create a new folder. Use an arbitrary name for the folder. For example:/opt/mapr_51
  3. Create a file in this folder named mapr-clusters.conf.
  4. Add the following line to this file: maprdemo:7222
    Note: maprdemo is the host name or IP address of the VM where the MapR Sandbox is running.
