[jira] [Created] (MAPREDUCE-6235) Bundle and compress files passed with -libjars prior to uploading and distributing

Dustin Cote created MAPREDUCE-6235:
--------------------------------------

             Summary: Bundle and compress files passed with -libjars prior to uploading and distributing
                 Key: MAPREDUCE-6235
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6235
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: distributed-cache, mrv2
    Affects Versions: 2.6.0
            Reporter: Dustin Cote
            Priority: Minor


To improve performance, we should upload jars flagged by -libjars as a single bundle and expand on arrival instead of uploading the jars one by one.   This would also reduce network overhead of using the -libjars option.
