[Bigdata-developers] Question on setup for new service tests

[Bryan T. <br...@sy...>]

Brian,

I am going to be setting up some new tests suites for quorum dynamics as part of HA.  Given a replication factor of k for some logical service, the minimum number of services in a quorum for that service is (k+1)/2.  For these tests, the focus will be on recognizing changes in the quorum membership (adding or dropping a service in a quorum without having the #of services fall beneath the minimum required for a quorum) and quorum dynamics (when the #of services falls beneath the minimum for a quorum and when a new quorum is formed). The initial implementation of the QuorumManager (the class which recognizes changes in the quorum membership and in make/break of quorums) will be over zookeeper.  I was wondering if you had any best practices for new test suites using jini and/or zookeeper which you would like to recommend.

Thanks,
Bryan
