Siddharth Seth commented on TEZ-1119:
-------------------------------------
Thinking on this some more, I think a client library in Tez to push events
linked to a specific construct (Vertex, VertexPlugin, Task, etc) works well -
almost equivalent to custom history events. The library would hide details of
where the data is being pushed from. Client usage would like do a push from the
AM, similarly for task changes.
Tez doesn't get into the business of pushing this data out in that case -
whether it's specific Vertex payloads, or specific task payloads. It's up to
Applications to make use of this, if they really need it. [~hitesh], thoughts ?

> Applications like Pig rely heavily on configurations bundled in as part of
> the user payload for debugging. This requires each Input/Output/Processor's
> user payload to be converted into something that easily consumable by the UI
> layer to be displayed back to the user as meaningful data.
