-------------------------------------

             Summary: MR AM should add working directory to LD_LIBRARY_PATH
                 Key: MAPREDUCE-6021
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6021
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mr-am
    Affects Versions: 2.4.1
            Reporter: Jason Lowe


Tasks implicitly pick up shared libraries added to the job because the task launch context explicitly adds the container working directory to LD_LIBRARY_PATH.  However the same is not done for the AM container which is inconsistent.  User code can run in the AM via output committer, speculator, uber job, etc., so the AM's LD_LIBRARY_PATH should have the container work directory for consistency with tasks.
