Master
Responsible for scheduling & managing jobs Scheduled computation should be close to the data if possible Bandwidth is expensive! (and slow) This relies on a Distributed File System (GFS / HDFS)! If a task fails to report progress (such as reading input, writing output, etc), crashes, the machine goes down, etc, it is assumed to be stuck, and is killed, and the step is re-launched (with the same input) The Master is handled by the framework, no user code is necessary
