hadoop2.2.0安装中遇到的错误:mapreduce.shuffle set in yarn.nodemanager.aux-services is invalid

hadoop安装中遇到的错误:mapreduce.shuffle set in yarn.nodemanager.aux-services is invalid

启动：

[hadoop@hadoop02 hadoop]$ yarn-daemon.sh start nodemanager
starting nodemanager, logging to /app/hadoop/hadoop-2.2.0/logs/yarn-hadoop-nodemanager-hadoop02.out

查看进程

[hadoop@hadoop02 hadoop]$ jps
4962 Jps
4405 DataNode
4932 NodeManager

再查一次nodemanager又没了

[hadoop@hadoop02 hadoop]$ jps
4405 DataNode
4997 Jps

解决办法 ：

在1个网站上找到了解决方法，（网络忘了没记）
urg, my copy/paste was botched up but hopefully this still makes sense. The value mapreduce.shuffle is now mapreduce_shuffle and the name yarn.nodemanager.aux-services.mapreduce.shuffle.class is now yarn.nodemanager.aux-services.mapreduce_shuffle.class




是yarn.site.xml参数配置的问题


yarn.nodemanager.aux-services.mapreduce_shuffle.class部分的错误


正确的是这样：
<property>
<name>yarn.nodemanager.aux-services.mapreduce_shuffle.class</name>
<value>mapreduce_shuffle</value>
 <description>shuffle service that needs to be set for Map Reduce to run </description>
  </property>
