Subject How to open DEBUG level for YARN application master ?
Date Mon, 22 Apr 2013 12:51:43 GMT
Hi

How do I open the DEBUG level for YARN application master  process ?
I couldn't find the relevant configuration the set (probably need to add them somewhere).

ps -ef | grep java | grep yarn
yarn     12585 29113  0 15:33 ?        00:00:00 /bin/bash -c /usr/java/jre1.6/bin/java -Dlog4j.configuration=container-log4j.properties
-Dyarn.app.mapreduce.container.log.dir=/var/log/hadoop-yarn/containers/application_1366187149316_0049/container_1366187149316_0049_01_000001
-Dyarn.app.mapreduce.container.log.filesize=0 -Dhadoop.root.logger=INFO,CLA -Xmx1024m org.apache.hadoop.mapreduce.v2.app.MRAppMaster
1>/var/log/hadoop-yarn/containers/application_1366187149316_0049/container_1366187149316_0049_01_000001/stdout
2>/var/log/hadoop-yarn/containers/application_1366187149316_0049/container_1366187149316_0049_01_000001/stderr


I'm using following YARN version
# rpm -qa | grep yarn
hadoop-yarn-nodemanager-2.0.0+922-1.cdh4.2.0.p0.12.el5
hadoop-yarn-nodemanager-2.0.0+88-1.cdh4.0.0.p0.26.el5
hadoop-yarn-2.0.0+922-1.cdh4.2.0.p0.12.el5
