org.apache.tez.dag.api.EdgeManagerPlugin.routeInputSourceTaskFailedEventToDestination()

Return the routing information to inform consumers about the failure of a source task whose outputs have been potentially lost. The return map has the routing information. The failure notification event will be sent to every task index in the key of the map. Every physical input in the value for that task key will receive the failure notification. This method will be called once for every source task failure and information for all affected destinations must be provided in that invocation. @param sourceTaskIndex Source task @param destinationTaskAndInputIndices Map via which the routing information is returned

    Assert.assertEquals(2, targets.size());
    for (Map.Entry<Integer, List<Integer>> entry : targets.entrySet()) {
