linux - 将文件从 linux 本地文件系统复制到 HDFS 时出错

Question

它的单节点集群在我开始时没有遇到任何问题，我还检查了所有守护进程的日志。

但是当我将数据从我的本地 linux 文件系统复制到 HDFS 文件系统时，它抛出一个异常提示；org.apache.hadoop.hdfs.DFSClient:DataStreamer 异常:java.lang.IllegalArgumentException:不包含有效的主机:端口权限:0:0:0:0:0:0:0:1:50010

请查看附件日志；

检查您的 mapred-site.xml。它应该包含有效的跟踪器条目。当然，主机和端口值应该根据您的系统进行更改。

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