Configuring log aggregation

Log aggregation is enabled by default. You can configure it using Cloudera Manager.

In Cloudera Manager, select the YARN service.
Click the Configuration tab.
Select the Log Aggregation filter under Category.
Every log aggregation related property is displayed.
Find the Enable Log Aggregation property and ensure that it is selected, meaning that log aggregation is enabled.
Configure the log aggregation properties as applicable.

The remote-app-log-dir and remote-app-log-dir-suffix configuration properties are not backward compatible. If you change their value later, the logs of applications that are already finished cannot be read.
Click Save Changes.
