在客户端 - 服务器模式下使用Apache Ignite

我正在尝试使用客户端服务器模式评估Apache Ignite。我有使用Hazelcast和Infinispan的一些经验，所以我来自IMDG背景。

我在客户端 - 服务器模式下使用Ignite的初步经验并不是很顺利。我可能听起来很自以为是，但我觉得大多数高级用例都适用于嵌入式服务器模式。

问题：

我确实有很多，但我正在发布我现在面临的那个。我使用的是v2.1.0。我正在尝试利用Ignite的durable memory功能。所以我在服务器配置中启用了持久性，如文档中所述。

<property name="persistentStoreConfiguration">
    <bean class="org.apache.ignite.configuration.PersistentStoreConfiguration"/>
</property>

现在，当我尝试从客户端连接时，使用代码

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);

我得到以下异常：

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.getOrCreateCache0(IgniteKernal.java:2837)
at org.apache.ignite.internal.IgniteKernal.getOrCreateCache(IgniteKernal.java:2824)

如果我设置ignite.activate(true)，代码会挂起（阻止？等待？）。为什么我的客户端（我假设）不作为数据节点参与，需要表现为一个？我在这里错过了什么吗？任何帮助将不胜感激。

这是我在服务器上看到的例外情况。

拓扑快照[ver = 5，服务器= 1，客户端= 0，CPU = 4，堆= 0.13GB]

您已启动Ignite服务器节点，堆内存太小（128mb），请尝试增加它（参数-Xmx＆amp; -Xms）。

此外，默认情况下，Ignite尝试在计算机上为其分配所有物理内存的0.8（pageMemory）。因此，如果要在同一台计算机上启动多个节点，则需要为节点配置MemoryPolicy。
