【解决】exited with a non-zero exit code 1

 

安装好集群后运行hadoop-mapreduce-examples.jar 报错，比对cdh配置后，发现少了yarn.application.classpath，conf目录一定要配置，否则也会出现以上错误。

 

yarn-site.xml添加

  <property>
     <name>yarn.application.classpath</name>
     <value>
          /etc/hadoop/conf,
          /usr/lib/hadoop/*,
          /usr/lib/hadoop/lib/*,
          /usr/lib/hadoop-hdfs/*,
          /usr/lib/hadoop-hdfs/lib/*,
          /usr/lib/hadoop-mapreduce/*,
          /usr/lib/hadoop-mapreduce/lib/*,
          /usr/lib/hadoop-yarn/*,
          /usr/lib/hadoop-yarn/lib/*
     </value>
</property>
