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
