-------------------------------------
Summary: Add synchronous validation for all types of Calls.
Key: MESOS-5301
URL: https://issues.apache.org/jira/browse/MESOS-5301
Project: Mesos
Issue Type: Improvement
Reporter: Anand Mazumdar
Currently, we do a best effort validation for all calls sent to the master from
the scheduler by invoking {{validation::scheduler::call::validate(call,
principal)}}. This is a generic validation helper for all calls. However, for
more coarse grained validation for a particular call, we invoke the validation
as part of the call handle itself.
{code}
Option<Error> validationError = roles::validate(frameworkInfo.role());
{code}
This in turn makes all validations asynchronous i.e. the framework gets them as
{{Event::ERROR}} events later. It would be good if such validations can be
handled while processing the {{Call}} message itself synchronously.
