[jira] [Created] (HADOOP-12612) Filesystem spec doesn't declare requirements for modtime on rename()

Steve Loughran created HADOOP-12612:
---------------------------------------

             Summary: Filesystem spec doesn't declare requirements for modtime on rename()
                 Key: HADOOP-12612
                 URL: https://issues.apache.org/jira/browse/HADOOP-12612
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs
    Affects Versions: 2.8.0
            Reporter: Steve Loughran
            Priority: Minor


The FS spec doesn't cover whether or not {{rename()} of a file should change its modtime.

* HDFS does update its modtime.
* local experiments with OSX hfs+ show that it doesn't appear to change there
* There's nothing in the FS tests which appear to look at this.
