Reading properties from appConfig.json

Hello,

Is there an example on how to read component properties from appConfig.json
from the agent Python script.

Our current code to read the config is here:

https://github.com/DataTorrent/koya/blob/master/koya-slider-package/package/scripts/params.py


And we would like to read the Kafka broker.id from the per broker config
block rather than flatten it in global scope, as we currently do:

https://github.com/DataTorrent/koya/blob/master/koya-slider-package/appConfig-default.json

It would then look like this:

"components": {
    "BROKER0": {
        "broker.id" "0"
    },
    "BROKER1": {
       "broker.id": "1"
    },
    "slider-appmaster": {
      "jvm.heapsize": "256M"
    }
  }


Thanks,
Thomas
