jsr203-hadoop provide NIO 2 access to your HDFS cluster. For example, you can build URI starts with hdfs://<namebode>:<port> and use standard NIO API :

URI uri = new URI("hdfs://" + host + ":" + port + "/somefile");
Path file = Paths.get(uri);
System.out.println("File [" + file.toString() + "] exists = '" + Files.exists(file) + "'");
