类 org.apache.ignite.IgniteException：无法执行该操作，因为集群处于非活动状态

Question

在摆弄了基本集群之后，我通过在新集群中添加以下配置，尝试了 Ignite 中的本机持久性的另一个示例。

    <!-- Enabling Apache Ignite Persistent Store. -->
    <property name="dataStorageConfiguration">
        <bean class="org.apache.ignite.configuration.DataStorageConfiguration">
            <property name="defaultDataRegionConfiguration">
                <bean class="org.apache.ignite.configuration.DataRegionConfiguration">
                    <property name="persistenceEnabled" value="true"/>
                </bean>
            </property>
        </bean>
    </property>

但是，我无法执行创建/插入/更新/删除操作。我面临以下错误：

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.active(true).

任何帮助将不胜感激。

如果使用持久性，则需要显式激活集群。请参阅此处的详细信息：https ://apacheignite.readme.io/docs/cluster-activation
