Description

The recent API that is being released in Storm UI with 0.9.2 is great, but it'd be useful if the API supported an optional ?callback parameter that would provide a wrapped JSON-P response for all endpoints.

Example:

GET https://my-storm-head.cogtree.com/api/v1/cluster/summary?callback=myFunction

myFunction({"stormVersion":"0.9.2-incubating","nimbusUptime":"4m 55s","supervisors":2,"slotsTotal":32,"slotsUsed":0,"slotsFree":32,"executorsTotal":0,"tasksTotal":0});

This would allow users to write clients similar to elasticsearch-head (which I was hoping to build) where they could use a single UI to manage multiple Storm environments.

Having a JSON-P ?callback param would allow clients to get around browsers enforcing same-origin policies.

The JSON-P site has examples of valid callback parameters:

functionName({JSON});

obj.functionName({JSON});

obj["function-name"]({JSON});
