Example 1 with SharedDiscoveryService

use of org.neo4j.causalclustering.discovery.SharedDiscoveryService in project neo4j by neo4j.

the class ClusterSeedingIT method shouldSeedNewMemberFromEmptyIdleCluster.

@Test
public void shouldSeedNewMemberFromEmptyIdleCluster() throws Throwable {
    // given
    cluster = new Cluster(testDir.directory("cluster-b"), 3, 0, new SharedDiscoveryService(), emptyMap(), backupParams(), emptyMap(), emptyMap(), Standard.LATEST_NAME);
    cluster.start();
    // when: creating a backup
    File backupDir = createBackup(cluster.getCoreMemberById(0).database(), "the-backup");
    // and: seeding new member with said backup
    CoreClusterMember newMember = cluster.addCoreMemberWithId(3);
    fsa.copyRecursively(backupDir, newMember.storeDir());
    newMember.start();
    // then
    dataMatchesEventually(DbRepresentation.of(newMember.database()), cluster.coreMembers());
}

Example 2 with SharedDiscoveryService

use of org.neo4j.causalclustering.discovery.SharedDiscoveryService in project neo4j by neo4j.

the class ClusterSeedingIT method setup.

@Before
public void setup() throws Exception {
    fsa = fileSystemRule.get();
    backupCluster = new Cluster(testDir.directory("cluster-for-backup"), 3, 0, new SharedDiscoveryService(), emptyMap(), backupParams(), emptyMap(), emptyMap(), Standard.LATEST_NAME);
    cluster = new Cluster(testDir.directory("cluster-b"), 3, 0, new SharedDiscoveryService(), emptyMap(), emptyMap(), emptyMap(), emptyMap(), Standard.LATEST_NAME);
    baseBackupDir = testDir.directory("backups");
}

Example 3 with SharedDiscoveryService

use of org.neo4j.causalclustering.discovery.SharedDiscoveryService in project neo4j by neo4j.

    // given
    cluster = new Cluster(testDir.directory("cluster-b"), 3, 0, new SharedDiscoveryService(), emptyMap(), backupParams(), emptyMap(), emptyMap(), Standard.LATEST_NAME);
    cluster.start();
    createEmptyNodes(cluster, 100);
    // when: creating a backup
    File backupDir = createBackup(cluster.getCoreMemberById(0).database(), "the-backup");
    // and: seeding new member with said backup
    CoreClusterMember newMember = cluster.addCoreMemberWithId(3);
    fsa.copyRecursively(backupDir, newMember.storeDir());
    newMember.start();
    // then
    dataMatchesEventually(DbRepresentation.of(newMember.database()), cluster.coreMembers());
