I am trying to evaluate Apache Ignite using the client server mode. I have some prior experiences in using Hazelcast and Infinispan, so I am coming from an IMDG background.
My initial experience on using Ignite in client-server mode is not very smooth. I might sound opinionated, but I felt that most of the advanced use cases are suitable from an embedded server mode perspective.
Question:
I do have many, but I am publishing the one which I am facing right now. I am using v2.1.0. I am trying to leverage the durable memory feature of Ignite. So I have turned on persistence in my server configuration, as described in documentation.
<property name="persistentStoreConfiguration"> <bean class="org.apache.ignite.configuration.PersistentStoreConfiguration"/> </property> Now when I try to connect from a client, with the code
Ignition.setClientMode(true); IgniteConfiguration cfg = new IgniteConfiguration(); //cfg.setPeerClassLoadingEnabled(true); TcpCommunicationSpi commSpi = new TcpCommunicationSpi(); commSpi.setSlowClientQueueLimit(1000); TcpDiscoverySpi discoverySpi = new TcpDiscoverySpi(); TcpDiscoveryVmIpFinder ipfinder = new TcpDiscoveryVmIpFinder(); ipfinder.setAddresses(Arrays.asList("localhost")); discoverySpi.setIpFinder(ipfinder); cfg.setCommunicationSpi(commSpi); cfg.setDiscoverySpi(discoverySpi); ignite = Ignition.start(cfg); //ignite.active(true); CacheConfiguration<String, Person> config = new CacheConfiguration<>("Person"); config.setCacheMode(CacheMode.PARTITIONED); //config.setOnheapCacheEnabled(true); //config.setEvictionPolicy(new LruEvictionPolicy<>(2)); ignite.getOrCreateCache(config); I get the following exception:
class org.apache.ignite.IgniteException: Can not perform the operation because the cluster is inactive. Note, that the cluster is considered inactive by default if Ignite Persistent Store is used to let all the nodes join the cluster. To activate the cluster call Ignite.activate(true). at org.apache.ignite.internal.IgniteKernal.checkClusterState(IgniteKernal.java:3712) at org.apache.ignite.internal.IgniteKernal.getOrCreateCache0(IgniteKernal.java:2837) at org.apache.ignite.internal.IgniteKernal.getOrCreateCache(IgniteKernal.java:2824) If I set ignite.activate(true), the code hangs (blocked? waiting?). Why does my client, which (I assume) do not participate as a data node, need to behave as one? Am I missing something here? Any help would be appreciated.
This is the exception I see on the server.
