Examples of Speculator

org.apache.hadoop.mapreduce.v2.app.speculate.Speculator
Speculator component. Task Attempts' status updates are sent to this component. Concrete implementation runs the speculative algorithm and sends the TaskEventType.T_ADD_ATTEMPT. An implementation also has to arrange for the jobs to be scanned from time to time, to launch the speculations.
