-----------------------------------------
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.
