[jira] [Created] (TEZ-514) Allow Inputs and Outputs to be specified per vertex

Siddharth Seth created TEZ-514:
----------------------------------

             Summary: Allow Inputs and Outputs to be specified per vertex
                 Key: TEZ-514
                 URL: https://issues.apache.org/jira/browse/TEZ-514
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth


Currently, Inputs and Outputs are configured for a vertex by specifying and Edge between two vertices. For root and leaf level vertices, it isn't possible to specify the Input and Output - this defaults to using MRInput and MROutput if no Inputs or Outputs, respectively, are found for a vertex.

It should be possible to specify Inputs/Outputs for root / non-root vertices - which are not connected to any other Vertex.
