> Currently, since all task cwds are created under a jobcache directory, users that need a job-specific shared directory for use as scratch space, create ../work. This is hacky, and will break when HADOOP-2115 is addressed. For such jobs, hadoop mapred should expose job.local.dir via localized configuration.
