问题 I am researching the algorithm that hazelcast uses to find the master node in multicast way.First I find the function to find master node: com.hazelcast.cluster.MulticastJoiner.findMasterWithMulticast() private Address findMasterWithMulticast() { try { if (logger.isFinestEnabled()) { logger.finest("Searching for master node. Max tries: " + maxTryCount.get()); } JoinRequest joinRequest = node.createJoinRequest(); while (node.isActive() && currentTryCount.incrementAndGet() <= maxTryCount.get())

由 萝らか妹 提交于 2020-01-25 20:23:32
问题 Based on this question, I'm trying to switch to the version 3.5-EA of Hibernate. Up to now I had a configuration like this: CacheConfiguration<K, V> configuration = new CacheConfig<K, V>() .setNearCacheConfig(new NearCacheConfig().setInMemoryFormat(InMemoryFormat.OBJECT)) .setExpiryPolicyFactory(createExpiryPolicyFactory(expiryDuration)); cache = cacheManager.createCache(cacheName, configuration); But now the setNearCacheConfig method is gone. There only exists a addNearCacheConfig on the

Prevent hazelcast to register EvictionListener on every node

由 陌路散爱 提交于 2020-01-24 21:05:08
问题 We currently having an issue that we configure a map entry listener for a specific map in the Hazelcast Config Bean. The problem we have is that the listener is instanciated on every node what make sense and is right with our implementation but actually it is not what we try to achieve. Is there a way to just add a listener on a map for just one cluster node or the cluster itself so when the entry is evicted there is only one listener registered to the map? To be clear: There are 12 Servers

Get the Master Ip Address from Hazelcast grid

由 ↘锁芯ラ 提交于 2020-01-24 10:29:07
问题 I would like to get the masterIpAddress use on the Hazelcast node in HazelcastInsatnceImpl from an instance HazelcastInsatnce. Somebody know how to do that? Thanks for your help 回答1: There is no real master in Hazelcast clusters. The oldest node plays some kind of a special role so you can imagine this one as the "master". To get this node get retrieve the first element from the memberlist. Cluster cluster = hazelcastInstance.getCluster(); Set<Member> members = cluster.getMembers(); Member
