Hello everyone, Gastón and I are working on enabling offer operation feedback for frameworks [1]. The 'id' field in an offer operation is used by the framework to enable status updates for that operation. This field is new in 1.5.0, and currently the master simply drops all operations which have this field set.
I'm updating the validation code to drop offer operations from SchedulerDriver-based frameworks when the 'id' field is set, since we are only adding this feature to the v1 scheduler API [2]. I have a patch up for this [3], and in addition to dropping the operation, the master sends a 'FrameworkErrorMessage', which will abort the SchedulerDriver. I wanted to check with people to see if they think that this is a reasonable use of the 'FrameworkErrorMessage', which we currently use mostly for failed subscription, in addition to a couple other cases. Another option would be to just silently drop operations from SchedulerDriver frameworks which have the 'id' field set. Currently, I'm opting for the more severe approach, which would inform the SchedulerDriver that it is using the API incorrectly by aborting it, with an informative error message. Let me know what you think, Greg [1] https://issues.apache.org/jira/browse/MESOS-8054 [2] https://docs.google.com/document/d/1GGh14SbPTItjiweSZfann4GZ6PCteNrn-1y4pxOjgcI/edit# [3] https://reviews.apache.org/r/63992/
