以持久存储模式启动点燃并使用 sqlline 控制台查询

Question

我正在使用以下配置以持久模式启动 ignite db -

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">
    <!--
        Alter configuration below as needed.
    -->
    <bean id="grid.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
     <!-- 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>
    </bean>
</beans>

此配置在 config/default-config.xml 文件中

之后我开始使用 sqlline 控制台 -

sqlline.sh --color=true --verbose=true -u jdbc:ignite:thin://127.0.0.1/

当我执行任何 DDL 查询时，在控制台中出现以下错误 -

java.sql.SQLException: 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).

    at sqlline.SqlLine.start(SqlLine.java:373)
    at sqlline.SqlLine.main(SqlLine.java:265)

我该如何激活集群？我在哪里调用 Ignite.active(true)?

注意：我在 ubuntu 18.0.4

中使用 Gridgrain ignite 社区版 8.7.5

最简单的方法是使用 control.sh 脚本，您可以在 bin 目录中找到它：

control.sh --activate

其他方式are documented.
