Kapil Arya updated MESOS-4916:
------------------------------
Story Points: 8
> Allow modules to express if they are multi-instantiable and thread safe.
> ------------------------------------------------------------------------

> Key: MESOS-4916

> Project: Mesos
> Issue Type: Task
> Reporter: Kapil Arya

>
> A module might be instantiated multiple time (e.g., multiple schedulers in
> the same Java process instantiating an authenticator module) within the same
> process. The current mechanism doesn't provide a way through the module API
> to forbid multiple instantiations. It is up to the module to check and return
> error on prior instantiation.
> Along similar lines, a module should be able to express thread-safety
> concerns. Typically, a module running in Master/Agent doesn't have to be
> concerned about thread safety if it uses libprocess API. However, we should
> investigate how it plays in the scheduler environment.
