在hadoop上運行字數

MY HADOOP在單節點上啓動。但是，在運行字數統計程序時，它會顯示以下錯誤。可能是什麼問題？在hadoop上運行字數

您需要使用Hadoop的腳本在bin文件夾和子的jar命令來調用你的工作，嘗試這個辦法：

[email protected]:~$ cd ~/hadoop-1.0.4 
[email protected]:~/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

我也從你的輸入和輸出路徑假設你的hadoop配置爲本地模式（因爲路徑是本地路徑：/ home/hduser）
