Question

我在伪节点模式下使用 Hadoop 2.7.0，在Fedora 22虚拟机上。几天前，MapReduce作业运行正常，但在安装了Oozie并修改了 yarn-site.xml 之后。我在运行Pi示例作业时遇到以下错误，并且我可能无法调试错误，

已编辑 - 我使用命令行运行作业，使用oozie工作流引擎运行 NOT ..命令 - hadoop jar 10 100

对此的任何帮助将非常感谢。

编辑 - 在

之前的yarn-site.xml
<property> <name>yarn.nodemanager.aux-services</name> <value>mapreduce_shuffle</value> </property> <property> <name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name> <value>org.apache.hadoop.mapred.ShuffleHandler</value> </property>

Answer 1

最后，我通过对 mapred-site.xml 进行以下更改来解决了这个问题，

<property>
    <name>mapreduce.jobhistory.webapp.address</name>
    <value>http://localhost:19888</value>
</property>

之后，这些工作完全正常。
