Listing the Configuration Files for Each Service

Each service on a node has one or more configuration files associated with it. The default version of each configuration file can be used as a template that you can modify as needed.

Files in the following directory contain the list of configuration files for each installed service: /opt/mapr/servicesconf/<service>.

Use the following command to display the configuration files or the directory that contains the configuration files for each service:
# cat /opt/mapr/servicesconf/<service>

For example, the following command displays the configuration files for NodeManager:

# cat /opt/mapr/servicesconf/nodemanager
hadoop/hadoop-2.7.4/etc/hadoop

The following table contains the configuration files and configuration file directories available for Hadoop and Hbase:
