[jira] [Updated] (MAPREDUCE-3883) Document
yarn.nodemanager.delete.debug-delay-sec configuration property
[ https://issues.apache.org/jira/browse/MAPREDUCE-3883?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eugene Koontz updated MAPREDUCE-3883:
-------------------------------------
Description:
If you are using Yarn's nodemanager, you can add to your configuration:
{noformat}
<property>
<name>yarn.nodemanager.delete.debug-delay-sec</name>
<value>10000000</value>
</property>
{noformat}
to save the environmental directories of the applications (by default in {{/tmp/nm-local-dir}}) that the nodemanager starts so that you can examine them later.
Set the above value long enough so that you have time to examine the contents before the nodemanager's {{DeletionService}} removes them.
This setting is defined in {{hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-common/src/main/java/org/apache/hadoop/yarn/conf/YarnConfiguration.java}}, and used in {{hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/java/org/apache/hadoop/yarn/server/nodemanager/DeletionService.java}}.
It's a useful configuration setting for developers, but seems not to be documented currently (see http://hadoop.apache.org/common/docs/r0.23.0/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-common/yarn-default.xml).
