Hi
With below configuration , log deletion should be triggered. You can see from
the log that deletion has been set to 3600 sec in NM like below. May be you can
check NM logs for the below log that give debug information.
“INFO
org.apache.hadoop.yarn.server.nodemanager.containermanager.loghandler.NonAggregatingLogHandler:
Scheduling Log Deletion for application: application_1428298081702_0008, with
delay of 10800 seconds”
But there is another configuration which affect deletion task is
“yarn.nodemanager.delete.debug-delay-sec”, default value is zero. It means
immediately deletion will be triggered. Check is this is configured?
<property>
<description>
Number of seconds after an application finishes before the nodemanager's
DeletionService will delete the application's localized file directory
and log directory.
To diagnose Yarn application problems, set this property's value large
enough (for example, to 600 = 10 minutes) to permit examination of these
directories. After changing the property's value, you must restart the
nodemanager in order for it to have an effect.
The roots of Yarn applications' work directories is configurable with
the yarn.nodemanager.local-dirs property (see below), and the roots
of the Yarn applications' log directories is configurable with the
yarn.nodemanager.log-dirs property (see also below).
