Configure Debug Delay
You can keep the application’s localized files and log directory on the local disk for a predefined time before the NodeManager deletes them.
This feature can be useful for example when there is a problem with the log aggregation feature or if you want to diagnose YARN application issues.
- In Cloudera Manager, select the YARN service.
- Click the Configuration tab.
- Search for deletion delay.
- Find the Localized Dir Deletion Delay property.
Define the delay time in seconds.
If you want to diagnose YARN application issues, set this property to a large value, for example to 600 seconds, to permit examination of these directories.
- Click Save Changes.
