    Description

      In the following code, if jobs corresponding to different users (X and Y) are localized simultaneously, it is possible that jobconf can be written to the wrong user's directory. (X's job.xml can be written to Y's directory)

        public void localizeJobFiles(JobID jobid, JobConf jConf,
            Path localJobTokenFile, TaskUmbilicalProtocol taskTracker)
            throws IOException, InterruptedException {
          localizeJobFiles(jobid, jConf,
              lDirAlloc.getLocalPathForWrite(JOBCONF, ttConf), localJobTokenFile,
              taskTracker);
        }
