Hi Hitesh,
The json structure looks fine. Does adding the source of the config
value make it useful? The current userPayloadAsText seems to be adding
source to the config values.
Thanks

Hi folks
As part of the Tez APIs, every object ( Input / Output / Processor /
EdgeManagerPlugin / VertexManagerPlugin ) can be associated with its own user
provided payload to set itself up. The format of this payload is not known to
Tez as it could be a java serialized object/protobuf/xml, etc. In a lot of
cases, this payload is usually a serialized configuration object. To make it
easy to expose this configuration aspects in the Tez UI, a setHistoryText API
was added to the UserPayload class.
This history text was meant to be something which could be displayed in the UI.
To make this more meaningful, I am proposing that we define a common standard
that everyone using this API can conform to. This will allow the UI to make
some assumptions about the structure and display the data in a more consumable
manner.
A possible standard could be:
- history text should be a json blob mapping to a json object containing
key-val pairs.
- the keys that should be used:
- description: value should be a simple string
- config: value should be an object in the format: { “key1”: “value1”,
“key2” : “value2”, … }
The above is not a final version or the recommended one. Folks like Jonathan and Prakash who are working on TEZ-8 may have stronger recommendations on the json structure.
@Gunther, @Rohini - any comments from the user point of view for exposing
Hive/Pig information in the Tez UI?
Comments/Questions/Suggestions?
thanks
