StormUIAPI

Python class covering Storm UI API REST

The Storm UI daemon provides a REST API that allows you to interact with a Storm cluster, which includes retrieving metrics data and configuration information as well as management operations such as starting or stopping topologies. The REST API returns JSON responses and supports JSONP. Clients can pass a callback query parameter to wrap JSON in the callback function.
