Jeff Zhang reassigned YARN-3755: -------------------------------- Assignee: Jeff Zhang > Log the command of launching containers > --------------------------------------- > > Key: YARN-3755 > URL: https://issues.apache.org/jira/browse/YARN-3755 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Jeff Zhang > Assignee: Jeff Zhang > > In the resource manager, yarn would log the command for launching AM, this is > very useful. But there's no such log in the NN log for launching containers. > It would be difficult to diagnose when containers fails to launch due to some > issue in the commands. Although use can look at the commands in the container > launch script file, this is an internal things of yarn, usually user don't > know that. In user's perspective, they only know what command they specify > when building yarn application. > {code} > 2015-06-01 16:06:42,245 INFO > org.apache.hadoop.yarn.server.resourcemanager.amlauncher.AMLauncher: Command > to launch container container_1433145984561_0001_01_000001 : > $JAVA_HOME/bin/java -server -Djava.net.preferIPv4Stack=true > -Dhadoop.metrics.log.level=WARN -Xmx1024m > -Dlog4j.configuratorClass=org.apache.tez.common.TezLog4jConfigurator > -Dlog4j.configuration=tez-container-log4j.properties > -Dyarn.app.container.log.dir=<LOG_DIR> -Dtez.root.logger=info,CLA > -Dsun.nio.ch.bugLevel='' org.apache.tez.dag.app.DAGAppMaster > 1><LOG_DIR>/stdout 2><LOG_DIR>/stderr > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
