org.apache.tez.dag.api.EdgeManager.routeDataMovementEventToDestination()
Return the routing information to inform consumers about the source task output that is now available. The return Map has the routing information. Key is the destination task physical input index and the value is the list of destination task indices for which the key input index will receive the data movement event. @param event Data movement event @param sourceTaskIndex Source task @param numDestinationTasks Total number of destination tasks @param inputIndicesToTaskIndices Map via which the routing information is returned
