> A cluster can have inconsistent affinity configuration if you created two
> nodes, one with affinity key configuration and other without it(in IgniteCfg
> or CacheCfg), both nodes will work fine with no exceptions, but in the same
> time they will apply different affinity rules to keys:
>
> {code:java}
> package affinity;
> import org.apache.ignite.Ignite;
> import org.apache.ignite.Ignition;
> import org.apache.ignite.cache.CacheAtomicityMode;
> import org.apache.ignite.cache.CacheKeyConfiguration;
> import org.apache.ignite.cache.CacheMode;
> import org.apache.ignite.cache.affinity.Affinity;
> import org.apache.ignite.configuration.CacheConfiguration;
> import org.apache.ignite.configuration.IgniteConfiguration;
> import org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi;
> import org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder;
> import java.util.Arrays;
> public class Test {
> private static int id = 0;
> public static void main(String[] args) {
> Ignite ignite = Ignition.start(getConfiguration(true, false));
> Ignite ignite2 = Ignition.start(getConfiguration(false, false));
> Affinity<Object> affinity = ignite.affinity("TEST");
> Affinity<Object> affinity2 = ignite2.affinity("TEST");
> for (int i = 0; i < 1_000_000; i++) {
> AKey key = new AKey(i);
> if(affinity.partition(key) != affinity2.partition(key))
> System.out.println("FAILED for: " + key);
> }
> System.out.println("DONE");
> }
> private static IgniteConfiguration getConfiguration(boolean
> withAffinityCfg, boolean client) {
> IgniteConfiguration cfg = new IgniteConfiguration();
> TcpDiscoveryVmIpFinder finder = new TcpDiscoveryVmIpFinder(true);
> finder.setAddresses(Arrays.asList("localhost:47500..47600"));
> cfg.setClientMode(client);
> cfg.setIgniteInstanceName("test" + id++);
> CacheConfiguration cacheCfg = new CacheConfiguration("TEST");
> cacheCfg.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
> cacheCfg.setCacheMode(CacheMode.PARTITIONED);
> if(withAffinityCfg) {
> cacheCfg.setKeyConfiguration(new
> CacheKeyConfiguration("affinity.AKey", "a"));
> }
> cfg.setCacheConfiguration(cacheCfg);
> cfg.setDiscoverySpi(new TcpDiscoverySpi().setIpFinder(finder));
> return cfg;
> }
> }
> class AKey {
> int a;
> public AKey(int a) {
> this.a = a;
> }
> @Override public String toString() {
> return "AKey{" +
> "a=" + a +
> '}';
