Apache Ignite容器因失败而重新启动：拓扑未初始化

Question

我用Ignite Helm chart stable/ignite version 2.7.6在Kubernetes上设置了我的Ignite集群。

但是很快我会收到类似的错误：

JVM will be halted immediately due to the fail ure: [failureCtx=FailureContext [type=SYSTEM_WORKER_TERMINATION, err=java.lang.IllegalStateExce ption: Topology is not initialized: app-profiles]]

结果，Ignite Kubernetes容器一次又一次地重新启动。

相关的缓存app-profiles的配置如下：

<bean class="org.apache.ignite.configuration.CacheConfiguration">
   <property name="name" value="app-profiles" />
   <property name="cacheMode" value="LOCAL" />
   <property name="onheapCacheEnabled" value="true" />
   <property name="evictionPolicy">
      <bean class="org.apache.ignite.cache.eviction.lru.LruEvictionPolicy">
         <property name="maxSize" value="10000" />
      </bean>
   </property>
   <property name="expiryPolicyFactory">
      <bean id="expiryPolicy" class="javax.cache.expiry.CreatedExpiryPolicy" factory-method="factoryOf">
         <constructor-arg>
            <bean class="javax.cache.expiry.Duration">
               <constructor-arg value="SECONDS" />
               <constructor-arg value="43200" />
            </bean>
         </constructor-arg>
      </bean>
   </property>
</bean>

Answer 1

发现问题出在cacheMode LOCAL。以某种方式，LOCAL模式下的缓存无法初始化其拓扑（Ignite版本2.7.6）。只需将其替换为PARTITIONED cacheMode，问题就消失了，如下所示：

<bean class="org.apache.ignite.configuration.CacheConfiguration">
   <property name="name" value="app-profiles" />
   <!-- <property name="cacheMode" value="LOCAL" /> -->
   <property name="cacheMode" value="PARTITIONED" />
   <property name="onheapCacheEnabled" value="true" />
   <property name="evictionPolicy">
      <bean class="org.apache.ignite.cache.eviction.lru.LruEvictionPolicy">
         <property name="maxSize" value="10000" />
      </bean>
   </property>
   <property name="expiryPolicyFactory">
      <bean id="expiryPolicy" class="javax.cache.expiry.CreatedExpiryPolicy" factory-method="factoryOf">
         <constructor-arg>
            <bean class="javax.cache.expiry.Duration">
               <constructor-arg value="SECONDS" />
               <constructor-arg value="43200" />
            </bean>
         </constructor-arg>
      </bean>
   </property>
</bean>

并且cacheMode REPLICATED也应该起作用。
