MapR Control System

Describes how to use and access the MapR Control System (MCS).

The MapR Control System allows you to manage the cluster through a comprehensive graphical user interface, including nodes, volumes, users, and alarms

Browser Compatibility

The MapR Control System is web-based, and works with the following browsers:

  • Chrome
  • Safari
    • Version 5.1 and below with unsigned or signed SSL certificates
    • Version 6.1 and above with signed SSL certificates
  • Firefox 3.0 and above
  • Internet Explorer 10 and above

Launching MapR Control System

To use the MapR Control System (MCS), navigate to the host that is running the WebServer in the cluster. MapR Control System access to the cluster is typically via HTTP on port 8080 or via HTTPS on port 8443.You should disable pop-up blockers in your browser to allow MapR to open help links in new browser tabs.

The first time you open the MCS via HTTPS from a new browser, the browser alerts you that the security certificate is unrecognized. This is normal behavior for a new connection. Add an exception in your browser to allow the connection to continue.
