Subject [jira] [Commented] (HDFS-2436) FSNamesystem.setTimes(..) expects the path is a file.
Date Wed, 21 Dec 2011 08:23:30 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2436?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13173943#comment-13173943
] 

Tsz Wo (Nicholas), SZE commented on HDFS-2436:
----------------------------------------------

> ... Directories do not have access times.

In our code, directories *do* have access times (and mtime) since the fields are defined in
INode but not INodeFile.  Also atime and mtime are returned in getFileInfo(..) for directories.
 It is quite confusing whether atime and mtime are supported for directories.    Let file
a JIRA to fix it.

> FSNamesystem.setTimes(..) does not work if the path is a directory.
> Arpit found this bug when testing webhdfs:

> settimes api is working when called on a file, but when called on a dir it returns a
404. I should be able to set time on both a file and a directory.
