-----------------------------------------

             Summary: Cluster can have inconsistent affinity configuration 
                 Key: IGNITE-7883
                 URL: https://issues.apache.org/jira/browse/IGNITE-7883
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 2.3
            Reporter: Mikhail Cherkasov
             Fix For: 2.5


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}
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);
        }

    }

    @NotNull 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++);

        if(withAffinityCfg) {
            CacheConfiguration cacheCfg = new CacheConfiguration("TEST");

            cacheCfg.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
            cacheCfg.setCacheMode(CacheMode.PARTITIONED);

            cacheCfg.setKeyConfiguration(new 
CacheKeyConfiguration("multiplan.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{" +
            "b=" + a +
            '}';
    }
}


{code}
