提前感谢。此问题以前已报告（），并已修复，可能尝试使用最新版本的pig 这个问题有时可以通过指定输入数据文件的路径来解决
e、 g.“/home/user/doc/info.txt”请编辑您的帖子，添加您输入数据的样本和完整的堆栈跟踪。你用的是哪个版本的Pig？我可以卸载r1、r2和r3。我只有在转储final时才得到错误。好的，但是您可以添加它吗？你用的是哪个版本的猪？我们需要更多信息来帮助您。它适用于我使用0.14.0。回到Pig 0.12.0，当Pig找不到文件时，它显示的不是一条正确的错误消息，而是您发布的内容。。。您确定在HDFS中使用了正确的路径吗？如果您在控制台中键入hadoop fs-cat info.txt，您会看到该文件的内容吗？是的，我可以看到该文件
