Ignite Cluster 在设置 loadBalancingSpi 后无法启动

Question

在我启动 Ignite 集群时配置 RR 负载平衡后，它失败并出现以下错误：

错误信息中说：

Required event types are disabled: TASK_FAILED, TASK_FINISHED, JOB_MAPPED

您可以通过 following the documentation 启用事件，但是，基本上，将如下内容添加到您的配置文件中：

<!-- Enable cache events. -->
<property name="includeEventTypes">
    <list>
        <util:constant static-field="org.apache.ignite.events.EventType.EVT_TASK_FAILED"/>
        <util:constant static-field="org.apache.ignite.events.EventType.EVT_TASK_FINISHED"/>
        <util:constant static-field="org.apache.ignite.events.EventType.EVT_JOB_MAPPED"/>
    </list>
</property>
