Hadoop清空回收站

This should give you output similar to this. Basically in a minute the trash will be emptied.

执行完命令后，回收站的数据不会立即被清理，而是先打了一个checkpoint。显示的是一分钟后清除。

实际验证，11T的数据需要好几分钟…..

16/09/18 10:57:04 INFO fs.TrashPolicyDefault: Namenode trash configuration: Deletion interval = 1 minutes, Emptier interval = 0 minutes.16/09/18 10:57:04 INFO fs.TrashPolicyDefault: Created trash checkpoint: /user/hdfs/.Trash/160918105704
