异常java.io.IOException:未能将路径：\tmp\hadoop user\mapred\staging\user1322875957\的权限设置为0700

我在使用mahout时遇到了一个异常。

---

我可以从数据库中获取数据，并使用该数据生成序列文件。之后，当我尝试对该序列文件进行矢量化时，会出现此异常。如何解决此问题？我正在使用Windows7

嗨，这是许可问题。您需要设置输入文件夹的所有读、写、执行权限。你的输入文件在HDFS上吗？我正在使用我的本地机器，我不知道它在HDFS上吗？但我有一台服务器，它是在HDFS中配置的hadoop，但我不知道如何在服务器中运行我的程序。您使用的是哪个hadoop发行版？它是Hortonworks数据平台（HDP2）还是Cloudera.Hadoop 0.18.0发行版
