Hello Hadoop community, I read about Hadoop framework ( http://hadoop.apache.org/core/docs/r0.16.3/mapred_tutorial.html) this phrase: "The Map-Reduce framework consists of a single master JobTracker and one slave TaskTracker per cluster-node..."
Is The Job Tracker (Master Node) unique and static for my cluster? Is The Job Tracker the same for each map/reduce run? If the response is positive, hadoop is different from map/reduce Google implementation. In Google Implementation the Master node is "one copies of program" (See MapReduce: Simplified Data Processing on Large Clusters). Thanks. -- Fabrizio
