我是新来的 nutch 试图整合 nutch 1.9 与 Hadoop 2.3.0-cdh5.1.0 得到如下例外情况：

Injector: java.lang.UnsupportedOperationException: Not implemented by the DistributedFileSystem FileSystem implementation

        at org.apache.nutch.crawl.Injector.main(Injector.java:370)

我有几个问题：我该如何解决这个问题。我还想知道我是否真的可以集成 hadoop 我用它来 nutch 1.9 ?
谢谢，桑德普
