Examples with NodeContext com.hazelcast.instance.impl.NodeContext used on opensource projects

Example 1 with NodeContext

use of com.hazelcast.instance.impl.NodeContext in project hazelcast by hazelcast.

the class TestHazelcastInstanceFactory method newHazelcastInstance.

/**
 * Creates a new test Hazelcast instance which is only allowed to connect to specified addresses:
 * <ul>
 * <li>{@code blockedAddresses} are blacklisted in its {@code MockJoiner}</li>
 * <li>connections to {@code blockedAddresses} are blocked by its {@code FirewallingConnectionManager}</li>
 * </ul>
 * This is handy in split-brain tests, when a new instance should be started on a specific network partition
 * of the split brain.
 *
 * @param address          the address to use as Member's address; if {@code null}, then uses the next address
 * @param config           the config to use; use {@code null} to get the default config
 * @param blockedAddresses addresses to which the new instance is allowed to communicate

Example 3 with NodeContext

use of com.hazelcast.instance.impl.NodeContext in project hazelcast by hazelcast.

the class InternalPartitionServiceImplTest method setup.

@Before

Example 4 with NodeContext

use of com.hazelcast.instance.impl.NodeContext in project hazelcast by hazelcast.

the class MembershipUpdateTest method memberJoinsEventually_whenMemberRestartedWithSameUuid_butMasterDoesNotNoticeItsLeave.

@Test

    MemberImpl member3 = getNode(hz3).getLocalMember();
    // A new member is restarted with member3's UUID.
    // Then after some time, member3 is terminated.
    // This is to emulate the case, member3 is restarted with preserving its UUID (using hot-restart),
    // but master does not realize its leave in time.
    // When master realizes, member3 is terminated,
    // new member should eventually join the cluster.
    Future<HazelcastInstance> future = spawn(() -> {
        NodeContext nodeContext = new StaticMemberNodeContext(factory, member3.getUuid(), factory.nextAddress());
