Setting Up Central Configuration from the Command-Line

MapR provides a central location where you can place customized configuration files for all the services running on the MapR cluster. As a result, you do not have to edit the configuration files on each node individually.

Default configuration files for each service are stored locally under /opt/mapr/. You can edit these files to create customized versions of the configuration files. To push these changes to other nodes in the cluster, copy the customized files to the mapr.configuration volume in the MapR-FS. When the pullcentralconfig script runs, it overwrites the local configuration file in /opt/mapr with the customized files on all nodes that the change applies to.

The mapr.configuration volume is mounted at maprfs://var/mapr/configuration.The mapr.configuration volume mount location is not configurable and is only used for central configuration.
