Eric Lin commented on HDFS-10352:
---------------------------------
Hi [~linyiqun], Thanks for your comment.
You have a valid point. Maybe we can create another getAccessTime() with
different number of parameters. Default to not checking children files, but if
forced, the code can check accordingly.
I understand its potential issue here if there are too many files under the
directory, but this is still a handy feature that can benefit some users, and
the edge case probably won't happen often.
Thanks

> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: fs
> Affects Versions: 2.6.4
> Reporter: Eric Lin
> Priority: Minor
>
> Currently FileStatus.getAccessTime() function will return 0 if path is a
> directory, it would be ideal that if a directory path is passed, the code
> will go through all the files under the directory and return the MAX access
> time of all the files.
