Examples of voldemort.client.rebalance.RebalancePlan

voldemort.client.rebalance.RebalancePlan
RebalancePlan encapsulates all aspects of planning a shuffle, cluster expansion, or zone expansion.

        assertTrue("Original and interm partition ids don't match",
                   originalPartitions.equals(finalPartitions));


        // Make sure that there is no data movement
        RebalancePlan rebalancePlan = ClusterTestUtils.makePlan(initialCluster,

                                                                storeDefs);
        // Make sure we have a plan
        assertEquals(rebalancePlan.getPlan().size(), 1);


        // Make sure there is no cross zones between zones in the plan
        assertEquals(rebalancePlan.getPartitionStoresMovedXZone(), 0);
        // Make sure there is no data movement between nodes
        assertEquals(rebalancePlan.getPartitionStoresMoved(), 0);
        for(Integer nodeId: interimCluster.getNodeIds()) {
            Set<Integer> remainingNodes = Sets.symmetricDifference(interimCluster.getNodeIds(),
                                                                   Sets.newHashSet(nodeId));

                assertTrue("Something went wrong as there is data movement between nodes",
                           rebalancePlan.getNodeMoveMap().get(nodeId, otherNodeId) == 0);
            }
        }


        // Also get the adjusted store definitions, with the zone dropped
        Cluster finalCluster = RebalanceUtils.dropZone(interimCluster, dropZoneId);
