Lin Yiqun commented on HDFS-10352:
----------------------------------
Hi, [~ericlin], I also agree with this. But I'm not sure about its performance
when one directory has lots of children files and it maybe costs some time to
traverse all children files and compare their time. And finally it return the
result slowly. I'm glad to work for this if someone else also support this
proposal.

> Key: HDFS-10352
> URL: https://issues.apache.org/jira/browse/HDFS-10352
> Project: Hadoop HDFS
> Issue Type: Bug
> 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.
