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.
