輸入路徑不存在：hdfs：// localhost：9000/user/rab/input

以下是我的工作輸出...在單模式下它運行良好，但在僞分佈模式下，它會拋出以下錯誤時間...我嘗試了很多，但無法滿足任何人的可能解決方案。我需要快速解決問題。在成功輸入路徑不存在：hdfs：// localhost：9000/user/rab/input

高度有義務...

我運行follwoing命令RAB @ RAB-VirtualBox的：〜/ hadoop的/ Hadoop的1.2.1 $斌/ hadoop的罐子Hadoop的例子 - *罐grep的輸入輸出 'DFS [AZ。] +' – RabNawazJadoon

。使用8021作爲hdfs端口 –

對於任何需要幫助的問題，您需要[mcve] – Cecilia

日誌輸出顯示錯誤：

「org.apache.hadoop.mapred.InvalidInputException：輸入路徑不存在：HDFS：//本地主機：9000 /用戶/ RAB /輸入」

你有稱爲目錄「下/用戶/ RAB的HDFS文件系統上輸入」？錯誤表明你不知道！該錯誤還表明它正在查看hdfs而不是本地文件系統。你可以用以下命令來檢查

「HDFS DFS -ls /用戶/ RAB」
，你使用的「bin/hadoop的罐子Hadoop的例子完整的命令 - *罐子grep的輸入輸出「DFS [ '] +'「希望命令的格式爲」hadoop jar jarfilename classname hdfsinputdirectory hdfsoutputdirectory「，其中classname是要運行的jar文件中類的名稱。
