示例1: testConvictAfterLeft
import org.apache.cassandra.config.DatabaseDescriptor; //导入方法依赖的package包/类
@Test
public void testConvictAfterLeft() throws UnknownHostException
{
StorageService ss = StorageService.instance;
TokenMetadata tmd = ss.getTokenMetadata();
tmd.clearUnsafe();
IPartitioner partitioner = new RandomPartitioner();
VersionedValue.VersionedValueFactory valueFactory = new VersionedValue.VersionedValueFactory(partitioner);
ArrayList<Token> endpointTokens = new ArrayList<>();
ArrayList<Token> keyTokens = new ArrayList<>();
List<InetAddress> hosts = new ArrayList<>();
List<UUID> hostIds = new ArrayList<>();
// we want to convict if there is any heartbeat data present in the FD
DatabaseDescriptor.setPhiConvictThreshold(0);
// create a ring of 2 nodes
Util.createInitialRing(ss, partitioner, endpointTokens, keyTokens, hosts, hostIds, 3);
InetAddress leftHost = hosts.get(1);
FailureDetector.instance.report(leftHost);
// trigger handleStateLeft in StorageService
ss.onChange(leftHost, ApplicationState.STATUS,
valueFactory.left(Collections.singleton(endpointTokens.get(1)), Gossiper.computeExpireTime()));
// confirm that handleStateLeft was called and leftEndpoint was removed from TokenMetadata
assertFalse("Left endpoint not removed from TokenMetadata", tmd.isMember(leftHost));
// confirm the FD's history for leftHost didn't get wiped by status jump to LEFT
FailureDetector.instance.interpret(leftHost);
assertFalse("Left endpoint not convicted", FailureDetector.instance.isAlive(leftHost));
}
示例2: setPhiConvictThreshold
import org.apache.cassandra.config.DatabaseDescriptor; //导入方法依赖的package包/类
