Method Detail

scheduleStage

public java.util.HashMap scheduleStage(java.lang.String wkflId,
                                       WorkflowStage stage,
                                       java.util.HashMap<java.lang.String,java.util.List<WorkerForScheduler>> globalSlots)

Specified by:

scheduleStage in class PolicyAbstract

globalSlots - available scheduling slots (workers)

Returns:

mapTasks. It will be empty if something failed
