无法在春季启动ignite客户端

Question

我有一个使用缓存机制的Spring云项目，我们通过在pom.xml中添加依赖关系，在应用中使用ignite缓存。我们通过在pom.xml中添加依赖关系，在应用中使用ignite缓存。

    <dependency>
        <groupId>org.apache.ignite</groupId>
        <artifactId>ignite-core</artifactId>
        <version>${ignite.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.ignite</groupId>
        <artifactId>ignite-spring</artifactId>
        <version>${ignite.version}</version>
    </dependency> 
    <dependency>
      <groupId>org.apache.ignite</groupId>
      <artifactId>ignite-rest-http</artifactId>
      <version>${ignite.version}</version>
    </dependency>

在属性标签中，我们提到ignite的版本是2.7.0(客户端)。ignite单机版服务器也有相同的版本，在同一台机器上运行。

谁能帮我解决这个问题。先谢谢你。

Answer 1

根据异常。

原因是：class org.apache.ignite.spi.IgniteSpiException。本地节点和远程节点的版本号不同（节点不会加入，Ignite不支持滚动更新，所以版本必须完全相同）[locBuildVer=2.8.0，rmtBuildVer=2.7. 0, locNodeAddrs=[test.test.com0:0:0:0:0:0:1, 127.0.0.1, 192.168.00.00], rmtNodeAddrs=[127.0.0.1], locNodeId=9aa05a68-b0f4-4fa9-b288-cc7c32caf691, rmtNodeId=14ea4223-b6e7-4084-b5a8-89481d99de53] 。

在Apache Ignite中不可能有一个混合集群。你应该选择2.8.0或2.7.0。

不过GridGain版确实允许你拥有一个多版本的集群。
