[jira] [Created] (MAPREDUCE-6153) Apply `mapreduce.admin.user.env' to AM

bc Wong created MAPREDUCE-6153:
----------------------------------

             Summary: Apply `mapreduce.admin.user.env' to AM
                 Key: MAPREDUCE-6153
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6153
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: applicationmaster
    Affects Versions: 2.5.0
            Reporter: bc Wong


Would be nice to be able to manipulate the AM's library path to include snappy. The `mapreduce.admin.user.env' seems perfect for this, except that it only affects the tasks. I think it's useful to have it apply to the AM as well.

Use case: I have a job that uses the output committer (which runs in the AM) to read the output file of the reducer, which is compressed using snappy.
