ChatHandleris an interface to provide RESTful APIs and some tasks are using it to communicate with other Druid modules. When a chatHanlder API is called,ChatHandlerResourcechecks the current running task is the expected callee. Before 0.14, it checkedtaskIdas it is, but after #6761, it encodestaskIdbefore comparing it. This breaks the backwards compatibility, especially when middleManagers of different versions are running in the same cluster. IftaskIddoesn't match,ChatHandlerResourcereturns null which just returnsNOT_FOUNDerror (404) with no message which makes debugging harder.This PR fixes the compatibility issue and improves
ChatHandlerResourceto returnBAD_REQUESTerror with a proper message whentaskIddoesn't match.
