我的 HADOOP 在单节点上启动。但是在运行字数统计程序时，它显示以下错误。可能是什么问题？

 hduser@reshmi-Inspiron-1545:~/hadoop-1.0.4$hadoop-examples-1.0.4.jar wordcount 
 /home/hduser/hadoop-1.0.4/dft /home/hduser/hadoop-1.0.4/dft-output 
 /home/hduser/hadoop-1.0.4/hadoop-examples-1.0.4.jar: line 1: $'PK\003\004':command not found

您需要使用 bin 文件夹中的 hadoop 脚本和 jar 子命令来调用您的作业，试试这个：

hduser@reshmi-Inspiron-1545:~$ cd ~/hadoop-1.0.4
hduser@reshmi-Inspiron-1545:~/hadoop-1.0.4$ bin/hadoop jar hadoop-examples-1.0.4.jar \
       wordcount /home/hduser/hadoop-1.0.4/dft \
       /home/hduser/hadoop-1.0.4/dft-output

我还从您的输入和输出路径中假设您的 hadoop 配置为本地模式（因为路径是本地路径：/home/hduser）
