             Summary: Response code and exception should be standardised for cube checking   
                 Key: KYLIN-3147
                 URL: https://issues.apache.org/jira/browse/KYLIN-3147
             Project: Kylin
          Issue Type: Improvement
            Reporter:  Kaige Liu
            Assignee:  Kaige Liu
            Priority: Minor


Checking if cubes exist or not is a common behaviour in some APIs. But we have lots of different responses for the same behaviour.
Let's take CubeController as an example. When can not find a cube with its name, someone gives a *400* as response code, someone returns *404*, and others send back a *500*. Not only HTTP response code is not standard, which kind of exception should be thrown is not unified as well. Still using the above example, we can find *IllegalArgumentException*, *BadRequestException*, *InternalErrorException*.
