Subject [jira] [Commented] (HDFS-10352) Allow users to get last access time of a given directory
Date Mon, 02 May 2016 07:03:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15266174#comment-15266174

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.

>             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.
