Question

它的单节点群集，而我开始没有遇到任何问题，我也为所有守护进程打了日志。

但是，虽然我将数据从我的本地linux文件系统复制到HDFS文件系统，但却抛出异常说法; org.apache.hadoop.hdfs.DFSClient：DataStreamer异常：java.lang.IllegalArgumentException：不包含有效的host：port authority：0：0：0：0：0：0：0：1：50010

请查看随附的日志;

Answer 1

检查您的mapred-site.xml。它应该有有效的跟踪器条目。当然应根据您的系统更改主机和端口值。

<property>
  <name>mapred.job.tracker</name>
  <value>host:port</value>
</property>
