我正在推出失败的Hadoop流媒体作业。启动它的行是：
hadoop jar $HADOOP_HOME/hadoop-streaming-2.6.0.2.2.5.3-1.jar -conf ~/HADOOP/conf/hadoop-cluster.xml -files aggregation_jobs -input /epcot -output /crowd_analytics/event_count/ -mapper "aggregation_jobs/streaming/event_count_map.py" -reducer "aggregation_jobs/streaming/event_count_reduce.py" -verbose >> output
hadoop-cluster.xml文件的内容如下：
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://fsdala12080.test.domain.com/</value>
</property>
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
<property>
<name>yarn.resourcemanager.address</name>
<value>fsdala12081.test.domain.com:8032</value>
</property>
</configuration>
我收到以下错误：

其中未知主机字符串的第一部分是我的本地计算机，它不在我正在谈论的集群中。顺便说一句，我可以从我的计算机与群集通信，并将文件从本地硬盘驱动器复制到该群集上的hdfs。为什么这可能不起作用的任何想法？为什么它会使我的本地主机达到峰值？我提交工作时有任何错误吗？任何指针都会有所帮助。
