Description

Mesos currently provides a task reconciliation mechanism with two modes of operation:

1. Explicit: status updates are sent back where the supplied task status is inconsistent with the master's knowledge.
2. Implicit: status updates are sent back for all non-terminal tasks.

As mentioned in the task reconciliation docs, both explicit and implicit reconciliation may be performed periodically to protect against data loss in the framework. It may be useful to add a mechanism by which the scheduler can supply a collection of known tasks, inducing a status update for all non-terminal tasks unknown to the scheduler.
