I agree, that seems like incorrect behaviour Scott - I would expect 404 too.

Hi all, 

I am curious as to the reasoning behind the 204 response for some API requests. For example: 


< HTTP/1.1 204 No Content
< Content-Type: application/json
< Access-Control-Allow-Origin: *
* Server Jetty(9.2.z-SNAPSHOT) is not blacklisted
< Server: Jetty(9.2.z-SNAPSHOT)
< x-api-url: /v1/dataset/3f8a1297-3259-4700-91fc-acc4170b27ce/metrics
< Accept-Ranges: bytes
< Date: Fri, 31 Jul 2015 17:46:32 GMT
< X-Varnish: 1108784184
< Age: 0
< Via: 1.1 varnish
< Connection: keep-alive

I assume this means that that dataset ID is not found?  If so, I would have expected a 404 perhaps.  There's no other info in the headers, so I'm not sure what other reason there is for no data returned (I realize a 204 should not return a body). I know this dataset ID used to return data, as I used it in examples for hitting the /dataset/*/metrics route  

In other APIs I get a 204 on a successful DELETE request - that's the only context I'm familiar with wrt 204's 

Thanks! Scott
