Jingcheng Du commented on HBASE-19650:
--------------------------------------
Thanks for the patch [~javaman_chen].
You encounter this issue when you run the mob file cleaner? Or do you have test
to re-produce this case?
As far as I know, it won't happen. The comparison is based on date, the
hour/minute/second are not included. In your description, the file date and
expired date are 2017-12-27, and the files in 2017-12-27 won't be archived.
> ExpiredMobFileCleaner has wrong logic about TTL check

> If today is 2017-12-28 00:00:01, and TTL is set to 86400, when
> MobUtils.cleanExpiredMobFiles execute, expireDate will be 1514304000749, but
> fileDate is 1514304000000. So the fileDate before the expireDate and mobfiles
> generated in is 2017-12-27 will all are deleted. But in fact, we want to
> delete files before 2017-12-27.
