示例2: cleanUpPartialOutputForTask

import org.apache.hadoop.mapreduce.TaskAttemptID; //导入方法依赖的package包/类
@Override
public void cleanUpPartialOutputForTask(TaskAttemptContext context)
    throws IOException {

  // we double check this is never invoked from a non-preemptable subclass.
  // This should never happen, since the invoking codes is checking it too,
  // but it is safer to double check. Errors handling this would produce
  // inconsistent output.

  LOG.info("cleanUpPartialOutputForTask: removing everything belonging to " +
      context.getTaskAttemptID().getTaskID() + " in: " +
      getCommittedTaskPath(context).getParent());

  final TaskAttemptID taid = context.getTaskAttemptID();
  final TaskID tid = taid.getTaskID();
  Path pCommit = getCommittedTaskPath(context).getParent();
  // remove any committed output
