hu yongfa commented on HDFS-14586:
----------------------------------
[~hexiaoqiao] good idea
may be it still need to get current time twice:
1. before calculate {{end}} time, this can avoid sleep more long time than
expect
2. before delete/create checkpoint loop, this can check current time with end
time.

>
> when trash timeout checkpoint coming, trash will delete the old folder first,
> then create a new checkpoint folder.
> as the delete action may spend a long time, such as 2 minutes, so the new
> checkpoint folder created late.
> at the next trash timeout checkpoint, trash will skip delete the new
> checkpoint folder, because the new checkpoint folder is
> less than a checkpoint interval.
