Job.local.dir to be exposed to tasks
------------------------------------
Key: HADOOP-2116
URL: https://issues.apache.org/jira/browse/HADOOP-2116
Project: Hadoop
Issue Type: Improvement
Components: mapred
Affects Versions: 0.14.3
Environment: All
Reporter: Milind Bhandarkar
Fix For: 0.16.0
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.
