> Requirements
> Java, some distributed systems knowledge, comfort implementing distributed
> systems protocols
> Description
> ZooKeeper servers detects the failure of other servers and clients by
> counting the number of 'ticks' for which it doesn't get a heartbeat from
> other machines. This is the 'timeout' method of failure detection and works
> very well; however it is possible that it is too aggressive and not easily
> tuned for some more unusual ZooKeeper installations (such as in a wide-area
> network, or even in a mobile ad-hoc network).
> This project would abstract the notion of failure detection to a dedicated
> Java module, and implement several failure detectors to compare and contrast
> their appropriateness for ZooKeeper. For example, Apache Cassandra uses a
> phi-accrual failure detector (http://ddsg.jaist.ac.jp/pub/HDY+04.pdf) which
> is much more tunable and has some very interesting properties. This is a
> great project if you are interested in distributed algorithms, or want to
> help re-factor some of ZooKeeper's internal code.
