Review request for mesos, Benjamin Hindman, Niklas Nielsen, and Vinod Kone.
Bugs: MESOS-1379
https://issues.apache.org/jira/browse/MESOS-1379
Repository: mesos-git
Description
-------
Currently frameworks must ask to reconcile a set of tasks explicitly, this
means that the tasks must be known to the framework.
In some cases, the framework may lose the information about a particular task
(bugs, data loss, etc). When this occurs, we do not provide a mechanism for the
state to be reconciled.
That is, the non-terminal tasks known to the Master / Slave that are unknown to
the framework will remain running. Status updates from these tasks are the only
way that frameworks will be informed of these tasks. This patch introduces the
notion of an "implicit" reconciliation request where the framework does not ask
about any explicit tasks. In this case, the master replies with all tasks
currently known.
