Description

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.
