      This issue restructures local job directory on the tasktracker.
      Users are provided with a job-specific shared directory (mapred-local/taskTracker/jobcache/$jobid/ work) for using it as scratch space, through configuration property and system property "job.local.dir". Now, the directory "../work" is not available from the task's cwd.

      This issue restructures local job directory on the tasktracker. Users are provided with a job-specific shared directory (mapred-local/taskTracker/jobcache/$jobid/ work) for using it as scratch space, through configuration property and system property "job.local.dir". Now, the directory "../work" is not available from the task's cwd.

      Description

      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.
