> A randomwriter job was running when the job tracker restarted. After the jobtracker restarted,
some tasktrackers were sent a reinit action. After this, some new tasks of the random writer
were scheduled to be run on the same task trackers. These failed in the job localization while
creating the work directory. However, the next attempts of the same job ran successfully and
the job succeeded. This happened in about 1% of the total number of tasks.
