示例1: runCount

import org.apache.hadoop.fs.shell.Count; //导入依赖的package包/类
private void runCount(String path, long dirs, long files, Configuration conf
                     ) throws IOException {
  ByteArrayOutputStream bytes = new ByteArrayOutputStream();
  PrintStream out = new PrintStream(bytes);
  PrintStream oldOut = System.out;
  System.setOut(out);
  Scanner in = null;
  String results = null;
  try {
    new Count(new String[]{path}, 0, conf).runAll();
    results = bytes.toString();
    in = new Scanner(results);
    assertEquals(dirs, in.nextLong());
    assertEquals(files, in.nextLong());
  } finally {
    if (in!=null) in.close();
    IOUtils.closeStream(out);
    System.setOut(oldOut);
    System.out.println("results:\n" + results);
