Lists the steps to configure and use central configuration of files.
HPE Ezmeral Data Fabric provides a central location where you can place customized configuration files for all the services running on the HPE Ezmeral Data Fabric 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 filesystem. When the pullcentralconfig script
runs, it overwrites the local configuration file in /opt/mapr with the
customized files on all nodes to which the change applies.
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.
Complete the following steps to use the Central Configuration
(pullcentralconfig script) to push a customized configuration file from
the mapr.configuration volume in filesystem to nodes in the
cluster.

|---|---|
Use this file on all nodes that use the configuration file unless a
node-specific file exists in the mapr.configuration
volume. |
/var/mapr/configuration/default/<directory path to the
configuration file> |
| Use this file for a specific node. | /var/mapr/configuration/nodes/<hostname>/<directory path to
the configuration file> |
mapr.configuration volume in the
directory that you created. For example, to create a directory to update the web
server configuration file, which is in /opt/mapr/conf, you would
create directory path /var/mapr/configuration/default/conf and then
copy the updated file to this directory.
pullcentralconfig script or wait until the script
acknowledges the update. For more information, see About the pullcentralconfig Script.
