Hadoop的錯誤：錯誤啓動的工作，糟糕的輸入路徑：文件不exist.Streaming命令失敗

我運行Hadoop集羣上的MRJob &我收到以下錯誤：Hadoop的錯誤：錯誤啓動的工作，糟糕的輸入路徑：文件不exist.Streaming命令失敗

我正在工作通過這個命令：

python3 /home/bhoots21304/Desktop/MrJobs-MR.py -r Hadoop的HDFS：//input3/File.txt

而且第一行說：發現沒有CONFIGS;迴歸自動配置

我擡頭看了一下。它說應該有/ etc /文件夾中的mrjob.conf文件的名稱，但它不存在於我的文件系統中的任何地方。我是否需要創建此文件。如果是的話，應該是什麼內容。

我使用在本文件中提及的指令安裝的hadoop：

此外hadoop-env.sh，芯-site.xml中，mapred-site.xml中，HDFS-site.xml中被配置很好，因爲它的工作，如果我只是運行一個簡單的worcount工作（不mRJob的）

你需要指定mrjob蟒蛇-bin和hadoop_streaming_jar（mRJob的使用「sudo的-H PIP3安裝mrjob」安裝）。 CONF。它應該看起來像這樣，取決於罐子的位置。

runners: 
    hadoop: 
     python_bin: python3 
     hadoop_streaming_jar: /usr/local/hadoop/share/hadoop/tools/lib/hadoop-streaming-2.7.3.jar

嘿，我面臨同樣的問題，但無法找到mrjob.conf文件。你能建議我在哪裏可以找到它嗎？ –
