Bikas Saha commented on TEZ-2234:
---------------------------------
Attaching patch that should fix the tests.
The patch enhances the API in a simple and generics manner by providing
input/output stats reporter interfaces for the tasks and a VertexStatistics
provider interface to the vertex manager plugins. This allow API evolution to
be restricted to these new interfaces. For now, only a setDataSize() has been
added to the reporters and a getDataSize() has been added to the providers.
That sums up the changes.
