He Xiaoqiao commented on HDFS-14586:
------------------------------------
[~jojochuang] Thanks for involving. I believe they are the same issue. I would
like to watch and review this patch.
[~huyongfa] Thanks for your report this issue and patch it again. Some minor
comment
a. Please rebase first if we want to patch to branch trunk.
b. I think another way is floor/format the checkpoint path date, then it will
not skip delete anymore. We should compare which way is more flexible.
c. Add unit test will be good to verify.
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 is
> less than a checkpoint interval.
