Arpit Agarwal commented on HDDS-3545:
-------------------------------------
I see thanks for the link [~maobaolong] and for reporting this. Yes this should
get addressed by HDDS-2939 when we have a better notion of directories or
prefixes. Certainly something for us to keep in mind as we work on HDDS-2939.

> URL: https://issues.apache.org/jira/browse/HDDS-3545
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: Ozone Filesystem
> Reporter: maobaolong
> Priority: Major
>
> After take a look at the code of JobHistory, i see jobhistory use
> `fs.getModificationTime()` to get the directory modification time, and use it
> as a condition of starting scan the job directories.
> But, for ozone, wile insert a child to a `directory`, the modification time
> of the `directory` don't update now.
> So we should update the modification time of `directory`, otherwise, MR
> Jobhistory and some other component which use the modification time of
> `directory` cannot work as expected.
