%description
    ZooKeeper is a centralized service for maintaining configuration
    information, naming, providing distributed synchronization, and
    providing group services. All of these kinds of services are used in
    some form or another by distributed applications. Each time they are
    implemented there is a lot of work that goes into fixing the bugs
    and race conditions that are inevitable. Because of the difficulty
    of implementing these kinds of services, applications initially
    usually skimp on them, which make them brittle in the presence of
    change and difficult to manage. Even when done correctly, different
    implementations of these services lead to management complexity when
    the applications are deployed.
