问题分析：The auxService:mapreduce_shuffle does not exist；yarn-site.xml配置文件有问题（注意单词拼写）

问题解决：vim /usr/local/hadoop/etc/hadoop/yarn-site.xml　　

<configuration>
  <property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value>
  </property>
  <property>
    <name>yarn.nodemanager.aux-services.mapreduce_shuffle.class</name>
    <value>org.apache.hadoop.mapred.ShuffleHandler</value>
  </property>
</configuration>
