我正在跟踪spring hadoop示例here，并尝试在mapReduce项目下运行它:
$ mvn clean package
$ sh ./target/appassembler/bin/wordcount
我收到此错误:

我可以运行hadoop命令，例如:
hdfs dfs -ls , hdfs dfs -put....,也可以访问:http://localhost:50070/dfshealth.html#tab-datanode但是为什么会发生这种异常？
最佳答案
确保在yarn-site.xml上具有以下内容
<property>
<name>yarn.resourcemanager.hostname</name>
<value>0.0.0.0</value>
</property>
