-------------------------------------
Summary: Implement Master state recovery using the registrar.
Key: MESOS-764
URL: https://issues.apache.org/jira/browse/MESOS-764
Project: Mesos
Issue Type: Improvement
Components: master
Reporter: Benjamin Mahler
Assignee: Benjamin Mahler
Fix For: 0.16.0
Using the registrar backed by ZooKeeper as a means for persistent, highly
available storage of the slave information will allow us to recover slave
information when a master is elected as a leader.
Having persistent slave information will allow the master to answer
reconciliation requests from frameworks in a correct and reliable manner. There
are currently cases where we cannot answer reconciliation requests in order to
avoid providing an incorrect answer (hints in MESOS-295).
It will also ensure that when we inform the world that a slave is removed, we
can enforce that as truth even with the presence of dropped messages and master
failovers.
