容器启动异常 exitCode=1 hadoop

Question

我在 windows 中安装了没有 cygwin 的 hadoop 2.8.1。我可以通过 start-all.cmd 来启动 hadoop。但是当我运行 wordcount.jar 时，我得到以下错误

命令：hadoop jar WordCount.jar WordCount G：/Hadoop/input 输出

用户日志中的标准错误文件仅包含 1 行：系统找不到指定的路径。我不明白它找不到哪个文件。

Answer 1

您正在提供一个本地文件作为输入文件。 Wordcount 程序需要 HDFS file/directory 作为输入，因此它失败了。

请将文件放到HDFS中再试一次。它应该有效。
