lucasbmiguel opened a new pull request #56:
URL: https://github.com/apache/incubator-marvin/pull/56
Currently, anything that's returned from the engine predictor.py `execute`
method, during a POST to /predictor, will be converted to a string. This
request introduces the ability for engines to return complex JSON types on HTTP
requests for /predictor.
#### How to test:
- Create a new engine and modify the `execute` method of your predictor.py
to return a dict with multiple fields.
- Start your engine http server and perform a client POST request to the
/predictor endpoint
#### Expected result
You should see a response that contains a JSON inside the "result" field of
the top-level response.
Similar to:
```
{
"result": {
"myPrediction": "predictedValue",
"additionalInfo": "toCarry",
"justANumber": 9
}
}
```
