Allow symlinking in LocalJobRunner DistributedCache
---------------------------------------------------
Key: MAPREDUCE-3871
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3871
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: distributed-cache
Reporter: Tom White
Assignee: Tom White
Attachments: MAPREDUCE-3871.patch
Currently the LocalJobRunner doesn't create symlinks for files in the
DistributedCache. It is safe to create symlinks if files of the same name don't
exist. LocalJobRunner should also delete the symlinks when the job has
completed.
