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

问题

照着一本书配置hadoop时启动nodemanager时报错

配置

<property>
    <!--
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce-shuffle</value>
    -->
    <name>yarn.nodemanager.aux-services.mapreduce_shuffle.class</name>
    <value>mapreduce-shuffle</value>
</property>

解决

开始时使用被注释掉的两行，报错：mapreduce.shuffle set in yarn.nodemanager.aux-services is invalid
。修改为下面两行后，nodemanager启动正常！
