FileUtil.stat2Paths介绍

[英]convert an array of FileStatus to an array of Path
[中]将FileStatus数组转换为Path数组

代码示例

代码示例来源:origin: org.apache.hadoop/hadoop-common

/**
 * convert an array of FileStatus to an array of Path.
 * If stats if null, return path
 * @param stats
 *          an array of FileStatus objects
 * @param path
 *          default path to return in stats is null
 * @return an array of paths corresponding to the input
 */

  return new Path[]{path};
 else
