FileUtil.copy在HA模式下工作hdfs

Question

我在HA模式下将文件从本地复制到hdfs，但它提供以下异常：

java.net.UnknownHostException: unknown host: nameservices
at org.apache.hadoop.ipc.Client$Connection.<init>(Client.java:195)
at org.apache.hadoop.ipc.Client.getConnection(Client.java:850)

at org.apache.hadoop.fs.FileSystem$Cache.get(FileSystem.java:1390)
at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:196)

我的HDFS写代码是：

        Path srcPath = new Path(
        LookupFileHelper.getLocalFileLocation(section));
        LOGGER.info("Uploading srcPath " + srcPath.toUri());
        FileSystem srcFS = FileSystem.get(srcPath.toUri(), conf);
        LOGGER.info("Uploading srcFS name" + srcFS.getName());
        LOGGER.info("Uploading srcFS " + srcFS);

        Path dstPath = new Path(section.getDestLocationHdfs());
        LOGGER.info("Uploading dstPath " + section.getDestLocationHdfs());
        URI uri = URI.create(section.getDestLocationHdfs());
        LOGGER.info("Uploading dstPath " + uri);
        FileSystem dstFS = FileSystem.get(uri, conf);
        LOGGER.info("Uploading dstPath " + dstFS);

        FileUtil.copy(srcFS, srcPath, dstFS, dstPath, false, conf);
