问题描述
请协助处理hadoop streaming的-file选项问题（在下面的链接中提到）。只是为了更新，我知道这个jar已经存在了，在我尝试hadoop-streaming为一个不同的类文件失败后，我正在尝试这个，所以为了确定类文件本身是否有问题或者我的方式使用它。如果你需要stderr文件，请让我知道。
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.
。
Problem with Hadoop Streaming -file option for Java class files.
推荐答案
-file发送jar文件，因为hadoop不支持多个jar文件（不在CLASSPATH中），请检查：
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:
这篇关于java.io.IOException：error = 2，Hadoop流中没有这样的文件或目录的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
