Review request for mesos, Benjamin Hindman and Vinod Kone.
Changes
-------
Rebase.
Bugs: MESOS-1453
https://issues.apache.org/jira/browse/MESOS-1453
Repository: mesos-git
Description
-------
Currently, we only reply to a reconciliation request when the task state
differs. This makes it difficult for a framework to implement reconciliation:
if the framework does not receive an update for the task, it cannot determine
if this was because the state is valid, or the slave was transitioning, or the
master has not recovered yet.
As a consequence of this, frameworks looking to reconcile tasks need to
continually retry at small intervals to compensate for the lack of ability to
differentiate the cases listed above.
If we always send back the latest status for each task requested, then the
frameworks can more easily implement reconciliation.
