-------------------------------------
Summary: Accept "application/recordio" type is rejected for master
operator API SUBSCRIBE call
Key: MESOS-7974
URL: https://issues.apache.org/jira/browse/MESOS-7974
Project: Mesos
Issue Type: Bug
Affects Versions: 1.2.1
Reporter: James DeFelice
The agent operator API supports for "application/recordio" for things like
attach-container-output, which streams objects back to the caller. I expected
the master operator API SUBSCRIBE call to work the same way, w/
Accept/Content-Type headers for "recordio" and
Message-Accept/Message-Content-Type headers for json (or protobuf). This was
not the case.
Looking again at the master operator API documentation, SUBSCRIBE docs
illustrate usage Accept and Content-Type headers for the "application/json"
type. Not a "recordio" type. So my experience, as per the docs, seems expected.
However, this is counter-intuitive since the whole point of adding the new
Message-prefixed headers was to help callers consistently request (and
differentiate) streaming responses from non-streaming responses in the v1 API.
Please fix the master operator API implementation to also support the
Message-prefixed headers w/ Accept/Content-Type set to "recordio".
Observed on ubuntu w/ mesos package version 1.2.1-2.0.1
