Configuring Log Locations

Setting the Cloudera Manager Server Log Location

By default the Cloudera Manager Server log is stored in /var/log/cloudera-scm-server/. If there is not enough space in that directory, you can change the location of the parent of the log directory:
  1. Stop the Cloudera Manager Server: 
    $ sudo service cloudera-scm-server stop
  2. Set the CMF_VAR environment variable in /etc/default/cloudera-scm-server to the new parent directory: 
    export CMF_VAR=/opt
  3. Create log/cloudera-scm_server and run directories in the new parent directory and set the owner and group of all directories to cloudera-scm. For example, if the new parent directory is /opt/, do the following: 
    $ sudo su
$ cd /opt
$ mkdir log
$ chown cloudera-scm:cloudera-scm log
$ mkdir /opt/log/cloudera-scm-server
$ chown cloudera-scm:cloudera-scm log/cloudera-scm-server
$ mkdir run
$ chown cloudera-scm:cloudera-scm run
  4. Restart the Cloudera Manager Server: 
    $ sudo service cloudera-scm-server start

Setting the Cloudera Manager Agent Log Location

By default the Cloudera Manager Agent log is stored in /var/log/cloudera-scm-agent/. If there is not enough space in that directory, you can change the location of the log file:
  1. Set the log_file property in the Cloudera Manager Agent configuration file: 
    log_file=/opt/log/cloudera-scm-agent/cloudera-scm-agent.log
  2. Create log/cloudera-scm_agent directories and set the owner and group to cloudera-scm. For example, if the log is stored in /opt/log/cloudera-scm-agent, do the following: 
    $ sudo su
$ cd /opt
$ mkdir log
$ chown cloudera-scm:cloudera-scm log
$ mkdir /opt/log/cloudera-scm-agent
$ chown cloudera-scm:cloudera-scm log/cloudera-scm-agent
  3. Restart the Agent: 
    $ sudo service cloudera-scm-agent restart
