%description 
Giraph implements a graph processing platform to run large scale algorithms (such as page rank, shared connections, personalization-based popularity, etc.) on top of Hadoop infrastructure. Giraph builds upon the graph-oriented nature of Pregel but additionally adds fault-tolerance to the coordinator process with the use of ZooKeeper as its centralized coordination service.
