示例1: scanIntermediateDirectory

import org.apache.hadoop.mapreduce.v2.jobhistory.JobHistoryUtils; //导入方法依赖的package包/类
/**
 * Scans the intermediate directory to find user directories. Scans these for
 * history files if the modification time for the directory has changed. Once
 * it finds history files it starts the process of moving them to the done 
 * directory.
 * 
 * @throws IOException
 *           if there was a error while scanning
 */
void scanIntermediateDirectory() throws IOException {
  // TODO it would be great to limit how often this happens, except in the
  // case where we are looking for a particular job.
  List<FileStatus> userDirList = JobHistoryUtils.localGlobber(
      intermediateDoneDirFc, intermediateDoneDirPath, "");
  LOG.debug("Scanning intermediate dirs");
  for (FileStatus userDir : userDirList) {
    String name = userDir.getPath().getName();
    UserLogDir dir = userDirModificationTimeMap.get(name);
    if(dir == null) {
      dir = new UserLogDir();
      UserLogDir old = userDirModificationTimeMap.putIfAbsent(name, dir);
