Hadoop 2中的HDFS文件路径问题

Question

I am getting fileNotFoundException in the mentioned line below. Earlier in Hadoop 1 this was functional. But now it throws a FileNotFoundException

        Path localManifestFolder;
        Path localManifestPath = new Path("hdfs:///WordCount/write/manifest");
        PrintWriter pw = null;
        FileSystem fs = null;
        try {
            URI localHDFSManifestUri = new URI("
                hdfs:///WordCount/write");
            fs = FileSystem.get(localHDFSManifestUri, conf);
            localManifestFolder = new Path("hdfs:///WordCount/write");
            FileStatus[] listOfFiles = fs.listStatus(localManifestFolder); // Getting Error in this line
        } catch (FileNotFoundException ex) {
          throw ex;
        }

Exception :

java.io.FileNotFoundException: File hdfs:/WordCount/write does not exist.

Please tell me why such thing is happening

If you do not have your core-site.xml on the classpath, then you need to specify the HDFS location (otherwise defaults to local filesystem)

For example

hdfs://namenode.fqdn:8020/WordCount
