This section contains reference information about various configuration files.

Configuration File Permissions

Files located in /opt/mapr/hadoop-2.x.x/etc/hadoop are owned by the root user account. To edit these files, you must be logged in as root user.

Automatic Rolloff of Old Configuration Files

Whenever you run configure.sh, the current warden.conf, mapr-clusters.conf, hibernate.cfg.xml, and db.conf configuration files are saved with the current timestamp appended to the name. They are saved to the following directory:

/opt/mapr/conf/conf.old

These configuration files are saved for backup purposes.
