James Peach commented on MESOS-4816:
------------------------------------
The isolator that I have that consumes {{TaskInfo}} labels was written for
Mesos 0.27. Since 0.28, {{prepare()}} gets a {{ContainerConfig}} which looks
like it should have the {{TaskInfo}}.
> Expose TaskInfo to Isolators

> URL: https://issues.apache.org/jira/browse/MESOS-4816
> Project: Mesos
> Issue Type: Improvement
> Components: modules, slave
> Reporter: Connor Doyle
>
> Authors of custom isolator modules frequently require access to the TaskInfo
> in order to read custom metadata in task labels.
> Currently, it's possible to link containers to tasks within a module by
> implementing both an isolator and the {{slaveRunTaskLabelDecorator}} hook,
> and maintaining a shared map of containers to tasks. This way works, but
> adds unnecessary complexity.
