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

             Summary: Add an interface to Input/Ouput Formats to obtain delegation tokens
                 Key: MAPREDUCE-5663
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5663
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth


Currently, delegation tokens are obtained as part of the getSplits / checkOutputSpecs calls
to the InputFormat / OutputFormat respectively.

This works as long as the splits are generated on a node with kerberos credentials. For split
generation elsewhere (AM for example), an explicit interface is required.
