很明顯應該是HADOOP_HOME的問題。如果HADOOP_HOME為空，必然fullExeName為null\bin\winutils.exe。解決方法很簡單，配置環境變量，不想重啟電腦可以在程序里加上：

1	System.setProperty( "hadoop.home.dir" , "E:\\Program Files\\hadoop-2.7.0" );

注：E:\\Program Files\\hadoop-2.7.0是我本機解壓的hadoop的路徑。

稍后再執行，你可能還是會出現同樣的錯誤，這個時候你可能會要怪我了。其實一開始我是拒絕的，因為你進入你的hadoop-x.x.x/bin目錄下看，你會發現你壓根就沒有winutils.exe這個東東。

於是我告訴你，你可以去github下載一個，地球人都知道的地址發你一個。

地址：https://github.com/srccodes/hadoop-common-2.2.0-bin

不要顧慮它的版本，不用怕，因為我用的最新的hadoop-2.7.0都沒問題！下載好后，把winutils.exe加入你的hadoop-x.x.x/bin下。
