TEZ-696. Explicit payloads for processor, input and output

[Bikas Saha <bi...@hortonworks.com>]

Hi,



TEZ-696 has been committed. When defining a vertex a processor payload
needs to be specified on the processor descriptor. When defining an edge
the input and output payloads need to be specified on the respective
descriptors. These payloads provide the initialization/configuration
information for the processor/input/output. Until now, Tez was implicitly
passing the processor payload to the input/output whenever the input/output
payload was missing. This could sometimes lead to inadvertent
misconfigurations between the input and output. This would also make
debugging hard when writing apps because things would magically work or not
work.



TEZ-696 removes the implicit copying. Payloads, if needed, must be
explicitly specified on the inputs/processors/outputs.
