Question

我正在关注spring hadoop示例here并尝试在mapReduce项目下运行它：

$ mvn clean package

$ sh ./target/appassembler/bin/wordcount

我收到了这个错误：

17:42:55,067  INFO doop.yarn.client.api.impl.YarnClientImpl: 174 - Submitted application application_1433091289740_0003 to ResourceManager at localhost/127.0.0.1:8032

我可以运行hadoop命令，例如：hdfs dfs -ls , hdfs dfs -put....,我也可以访问：http://localhost:50070/dfshealth.html#tab-datanode

但为什么会发生这种异常呢？

Answer 1

确保在yarn-site.xml上有以下内容

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