请帮助解决hadoop流的“-file”选项问题（在下面的链接中提到）。只是为了更新，我知道 jar 已经在那里，在我尝试 hadoop-streaming 不同的类文件失败后，我正在尝试此操作，以便确定类文件本身或我的方式是否有问题使用它。如果您需要 stderr 文件，请告诉我。
Java 类文件的 Hadoop Streaming -file 选项出现问题< /a>.
Please help with the "-file" option issue of hadoop streaming (mentioned in the link below). just to update, I know that the jar is already there, I am trying this after I tried hadoop-streaming for a different class file which failed, so to identify if there is something wrong with the class file itself or with the way I am using it. if you need the stderr file please let me know.

您不能真正使用 -file 来发送 jar，因为 hadoop 不支持多个 jar（不在 CLASSPATH 中），请检查 流媒体文档：
you can't really use -file to send over jars as hadoop doesn't support multiple jars (that were not already in the CLASSPATH), check the streaming docs:
要将多个 jar 文件添加到 CLASSPATH..，您可以使用 hadoop 教程（在页面上搜索单词“libjar”）。
To add more than one jar file to the CLASSPATH.. you could use the -libjars options as specified in the hadoop tutorial (search for the word "libjar" on the page).
