Subject [jira] [Created] (MAPREDUCE-4417) add support for encrypted shuffle
Date Tue, 10 Jul 2012 00:16:34 GMT
Alejandro Abdelnur created MAPREDUCE-4417:
---------------------------------------------

             Summary: add support for encrypted shuffle
                 Key: MAPREDUCE-4417
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4417
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: mrv2
    Affects Versions: 2.0.0-alpha
            Reporter: Alejandro Abdelnur
            Assignee: Alejandro Abdelnur
             Fix For: 2.0.1-alpha


Currently Shuffle fetches go on the clear. While Kerberos provides comprehensive authentication
for the cluster, it does not provide confidentiality. 

When processing sensitive data confidentiality may be desired (at the expense of job performance
and resources utilization for doing encryption).
