Central Configuration
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.
