ignite从2.6.0升级到2.7.5有报错

Question

@李玉珏 你好，想跟你请教个问题：
     之前我用的ignite2.6.0版本，用静态路由方式集群，服务内嵌到tomcat中启动没有问题，现在升级为2.7.5版本，启动tomcat报错：错误信息如下：

下面是配置信息：

<bean id="igniteConfig" class="org.apache.ignite.configuration.IgniteConfiguration">
        <!-- 配置为客户端节点(必须，否则默认为server) -->
        <!-- <property name="clientMode" value="true" /> -->
        <!-- 配置客户端节点名称 -->
        <property name="igniteInstanceName" value="igniteStart" />
        <!-- 客户端关闭metrics日志打印(value类型long 设置60*1000L即为1分钟刷新一次metrics日志，设置为0即关闭) -->
        <property name="metricsLogFrequency" value="0" />
        <!-- server重启时客户端自动重连(value时间内服务端若重启客户端会自动重连) -->
        <property name="networkTimeout" value="1000000" />

Answer 1

从2.6到2.7.5，版本是向下兼容的，至于你这个具体的错误，需要提供更详细的信息。
