> 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.
