我遇到了我的点燃集群的问题，客户端在启动期间一直挂起 . 此群集在k8s中运行，并且是3个节点
我创建了一个简单的缓存/近缓存，因为他们正在对其进行更改以衡量性能影响 . 这是客户端启动代码：
Ignition.setClientMode(true);
IgniteConfiguration igniteConfiguration = new IgniteConfiguration();
igniteConfiguration.setIncludeEventTypes(EventType.EVTS_ALL);
igniteConfiguration.setPeerClassLoadingEnabled(true);
TcpDiscoverySpi tcpDiscoverySpi = new TcpDiscoverySpi();
igniteConfiguration.setDiscoverySpi(tcpDiscoverySpi);
TcpDiscoveryIpFinder podResolver = getKubePodResolver();
tcpDiscoverySpi.setIpFinder(podResolver);
tcpDiscoverySpi.setJoinTimeout(30000);
tcpDiscoverySpi.setAckTimeout(30000);
tcpDiscoverySpi.setSocketTimeout(30000);
tcpDiscoverySpi.setNetworkTimeout(30000);
tcpDiscoverySpi.failureDetectionTimeoutEnabled(true);
try (Ignite ignite = Ignition.start(igniteConfiguration)) {
ignite.destroyCache("myCache");
NearCacheConfiguration<Integer, Integer> nearCfg = new NearCacheConfiguration<>();
nearCfg.setNearEvictionPolicy(new LruEvictionPolicy<>(5000));
nearCfg.setNearStartSize(5000);
CacheConfiguration<Integer, Integer> cacheConfiguration = new CacheConfiguration<Integer, Integer>("myCache");
cacheConfiguration.setOnheapCacheEnabled(false);
cacheConfiguration.setStatisticsEnabled(true);
cacheConfiguration.setWriteBehindEnabled(true);
cacheConfiguration.setCacheMode(CacheMode.PARTITIONED);
// toggling btwn partitioned and replicated
// cacheConfiguration.setCacheMode(CacheMode.REPLICATED);
cacheConfiguration.setQueryParallelism(3);
IgniteCache<Integer, Integer> cache = ignite.getOrCreateCache(cacheConfiguration, nearCfg);
在创建缓存之后，我运行get和puts来填充最多10k个条目 . 当我重新启动客户端它挂起 - 我可以通过简单地重新启动客户端来重现这一点 .
在客户端上运行线程转储时，我看到主线程挂在未来和关联的线程上
