public interface FlowStepStrategy<Config>
FlowStepconfiguration values before they are submitted to the underlying platform. Use a strategy instance to change the display name for a job, or in the case of Hadoop, the number of mapper or reducer instances. Note, to change the configuration information,
FlowStep.getConfig()must be called to get access to the current configuration. If any, the completed predecessor steps are provided so that the predecessors can be inspected via the
FlowStepStatsinterface for any information that may influence the current job. It is also possible to block submission of the job by blocking in this method.
