我使用 Spring Boot 应用程序创建了两个节点的集群。没有任何外部资源 - 只有内存中的 DB 和 Apache Ignite 作为分布式缓存。当一个节点已启动且第二个节点已 promise 启动时，我对两个节点进行了 tcp 转储和 JFR。
我在尝试启动的节点上看到了这个:
十秒仅获取字节。与此同时，该节点上的另一个 Ignite SPI 线程“tcp-disco-msg-worker”尝试从同一远程 IP 和端口读取数据，也花费了大约 10 秒。
同时，已经启动的第一个节点尝试执行相同的操作 - 读取一个字节大约十秒
因此，它们似乎试图同时读取彼此的消息并互相阻止 - 当此 SPI 线程尝试读取时，它无法写入答案。
但我在另一个具有两台服务器且应用程序及其配置完全相同的集群上没有看到这种行为 - 没有任何长读取。
有谁知道我的第一个集群出了什么问题以及为什么 Ignite 尝试在两个节点上同时读取有关拓扑的元信息？
主要问题是，我的第一个集群的一个节点上的 Ignite 经常失败，因为 SPI 线程决定集群处于 SEGMENTED 状态。 SPI 线程之所以会进入这种状态，是因为它在常规通信期间无法从其中一个节点获取元信息。
该集群似乎存在一些网络问题，但所有低级测试表明一切正常。
我知道他们说的是 SEGMENTED 状态 - 长 GC、网络问题等等。但我没有看到这样的事情。 SPI 线程中的套接字通信期间只是非常长的读取。而且它只在一个集群上。另一个具有相同配置的集群不会出现此类问题。
有人能给我建议我应该检查或测试什么吗？
UPD: 我的配置:
@Bean
public IgniteCache<String, WaveFile> getCache() {
log.info("Ignite addresses: " + Arrays.asList(igniteAddresses));
IgniteConfiguration conf = new IgniteConfiguration();
Slf4jLogger gridLog = new Slf4jLogger(log);
conf.setGridLogger(gridLog);
conf.setClientMode(false);
conf.setNetworkTimeout(networkTimeout);
conf.setClassLoader(WaveFile.class.getClassLoader());
TcpDiscoverySpi tcpDiscoverySpi = new TcpDiscoverySpi();
TcpDiscoveryVmIpFinder ipFinder = new TcpDiscoveryVmIpFinder();
ipFinder.setAddresses(Arrays.asList(igniteAddresses));
tcpDiscoverySpi.setIpFinder(ipFinder);
tcpDiscoverySpi.setAckTimeout(failureDetectionTimeout);
conf.setDiscoverySpi(tcpDiscoverySpi);
conf.setSqlConnectorConfiguration(null);
MemoryConfiguration memoryConfiguration = new MemoryConfiguration();
MemoryPolicyConfiguration memoryPolicyConfiguration = new MemoryPolicyConfiguration();
memoryPolicyConfiguration.setInitialSize(5L * 1024 * 1024 * 1024);
memoryConfiguration.setMemoryPolicies(memoryPolicyConfiguration);
conf.setMemoryConfiguration(memoryConfiguration);
Ignite ignite = Ignition.start(conf);
// Cache Config
CacheConfiguration<String, WaveFile> cacheConfig = new CacheConfiguration<>();
cacheConfig.setName(cacheName);
cacheConfig.setCacheMode(CacheMode.PARTITIONED);
cacheConfig.setWriteSynchronizationMode(CacheWriteSynchronizationMode.FULL_SYNC);
cacheConfig.setCopyOnRead(false);
cacheConfig.setEagerTtl(eagerTtl);
cacheConfig.setExpiryPolicyFactory(FactoryBuilder.factoryOf(
new TouchedExpiryPolicy(new Duration(TimeUnit.SECONDS, expirationPeriod))));
return ignite.getOrCreateCache(cacheConfig);
}
日志。你可以看到有 4 个节点，但实际上我只在其中两个节点上进行了测试。

最佳答案
问题是 DNS 中缺少集群主机名。更正此问题后，不再有十秒长的读取，并且集群至少在半天内仍能正常工作。
关于java - Ignite 启动时间过长，并且在应用程序运行时经常失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46961122/
