Document yarn.nodemanager.delete.debug-delay-sec configuration property -----------------------------------------------------------------------
Key: MAPREDUCE-3883 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3883 Project: Hadoop Map/Reduce Issue Type: Improvement Components: documentation Reporter: Eugene Koontz Priority: Minor Fix For: 0.23.2 If you are using Yarn's nodemanager, you can add to your configuration: {{ <property> <name>yarn.nodemanager.delete.debug-delay-sec</name> <value>10000000</value> </property> }} (set the {{<value>}} large enough so that you can examine the contents before the {{DeletionService}} deletes them). 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. 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). -- This message is automatically generated by JIRA.
