He Xiaoqiao commented on HDFS-14586:
------------------------------------

One thought about this issue. As you said, it still may be late to create 
checkpoint path, What about create one variable record {{new Date(now)}} before 
loop, then the following create using this date time only rather than get 
locally? FYI. Thanks again.

> 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 isĀ 
> less than a checkpoint interval.
