Example 16 with FTPClient

use of org.apache.commons.net.ftp.FTPClient in project hadoop by apache.

the class FTPFileSystem method open.

@Override
public FSDataInputStream open(Path file, int bufferSize) throws IOException {
    FTPClient client = connect();
    Path workDir = new Path(client.printWorkingDirectory());
    Path absolute = makeAbsolute(workDir, file);

        disconnect(client);
        throw new FileNotFoundException("Path " + file + " is a directory.");
    }
    client.allocate(bufferSize);
    Path parent = absolute.getParent();
    // Change to parent directory on the
    // server. Only then can we read the
    // file
    // on the server by opening up an InputStream. As a side effect the working
    // directory on the server is changed to the parent directory of the file.
    // The FTP client connection is closed when close() is called on the
    // FSDataInputStream.
    client.changeWorkingDirectory(parent.toUri().getPath());
    InputStream is = client.retrieveFileStream(file.getName());
    FSDataInputStream fis = new FSDataInputStream(new FTPInputStream(is, client, statistics));

        // which in turn will logout and disconnect from FTP server
        fis.close();
