I am new to Cloudera Hadoop.
I need to know how can I free space from Container Log Directories in Node Manager.
To review the state please
# df -h /var/log/hadoop-yarn
If no clean up is possible and there is sufficient disk space available then you can in decrease the alarm threshold in the CM > YARN > Configuration > Scope: Node Manager > Category: Monitoring > Log Directory Free Space Monitoring Percentage Thresholds configuration property.
