      Description

      if a directory named in mapred.local.dir is not writable at start-up, a ConcurrentModficationException is thrown. this is caused by calling remove on a collection that is being iterated over. patch MR2850.v1.3.patch from MAPREDUCE-2850 addresses this, but it hasn't been applied in the 1.0 releases.
