org.elasticsearch.cluster.routing.allocation.allocator.ShardsAllocator

A {@link ShardsAllocator} is the main entry point for shard allocation on nodes in the cluster.The allocator makes basic decision where a shard instance will be allocated, if already allocated instances need relocate to other nodes due to node failures or due to rebalancing decisions.

    @Test
    public void testNoRebalanceOnPrimaryOverload() {
        ImmutableSettings.Builder settings = settingsBuilder();
        AllocationService strategy = new AllocationService(settings.build(), randomAllocationDeciders(settings.build(),
                new NodeSettingsService(ImmutableSettings.Builder.EMPTY_SETTINGS), getRandom()), new ShardsAllocators(settings.build(),
                new NoneGatewayAllocator(), new ShardsAllocator() {


            @Override
            public boolean rebalance(RoutingAllocation allocation) {
                return false;
            }
