%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.
