                 Key: HADOOP-5470
                 URL: https://issues.apache.org/jira/browse/HADOOP-5470
             Project: Hadoop Core
          Issue Type: Improvement
          Components: util
    Affects Versions: 0.19.1, 0.19.0, 0.18.3, 0.18.2, 0.18.1, 0.18.0
            Reporter: Colin Evans
            Priority: Minor


For tools like jruby and jython, last modified times determine if a script gets 
recompiled.  Losing the correct last modified time causes some unfortunate 
recompilation race conditions when a job is running.
