在尝试在mapreduce项目下运行spring hadoop之后，我将在这里关注spring hadoop示例：

$ mvn clean package

$ sh ./target/appassembler/bin/wordcount

我有个错误：

我可以运行hadoop命令，例如： hdfs dfs -ls , hdfs dfs -put...., 我还可以访问： http://localhost:50070/dfshealth.html#tab-datanode 但为什么会发生这种异常呢？

确保在yarn-site.xml上有以下内容

<property>
    <name>yarn.resourcemanager.hostname</name>
    <value>0.0.0.0</value>
