--------------------------------
Summary: MR Jobhistory cannot work well with o3fs hadoop
compatible file system
Key: HDDS-3545
URL: https://issues.apache.org/jira/browse/HDDS-3545
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: Ozone Filesystem
Reporter: maobaolong
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.
