> import org.apache.hadoop.conf.*;
> import org.apache.hadoop.fs.*;
> import org.apache.hadoop.security.*;
> class Foo {
> public static void main(String args[]) throws Exception {
> FileSystem fs = FileSystem.get(new
> java.net.URI("webhdfs://<host>:14000/"), new Configuration());
> System.out.println(fs.listStatus(new Path("/"))[0]);
> java.io.OutputStream os = fs.create(new Path("/tmp/foo"));
> os.write('a');
> os.close();
> }
> }
> {code}
