The "ZooKeeper/PaxosRun" page has been changed by FlavioJunqueira. http://wiki.apache.org/hadoop/ZooKeeper/PaxosRun?action=diff&rev1=3&rev2=4 -------------------------------------------------- - = Example of Paxos run = + = Example: Paxos run = In this page, we show an example of a Paxos run that violates the primary order of messages. The basic idea is that if we have three proposers over time and three acceptors, we can have a situation in which a proposer proposes A and B, but only B is committed. For ZooKeeper, operations are state changes, and such cases can lead to inconsistent state. In this particular example, the state change B represents depends upon A, but A was not committed.
