Example 17 with InstanceId

use of org.apache.heron.spi.packing.InstanceId in project heron by twitter.

the class FirstFitDecreasingPackingTest method testScaleDownOneComponentRemoveContainer.

/**
 * Test the scenario where scaling down removes instances from containers that are most imbalanced
 * (i.e., tending towards homogeneity) first. If there is a tie (e.g. AABB, AB), chooses from the
 * container with the fewest instances, to favor ultimately removing  containers. If there is
 * still a tie, favor removing from higher numbered containers
