Apache Ignite升级

Question

我正在试验Apache Ignite 1.6和Ignite 2.1。

我能够创建一个集群，并使用Ignite1.6和基于ZooKeeper的发现。

我尝试在相同的节点上使用基于ZooKeeper的发现来创建Ignite2.1集群，但是失败了，错误如下。

我已经杀死了Ignite 1.6集群中的所有节点。

以下是错误消息：

            </property>
        </bean>
    </property>
   </bean>
</beans>

现在，无法启动这些集群中的任何一个。失败，并显示相同的错误消息。

如何解决此错误。

Answer 1

问题已解决。

在安装了Ignite 1.6的节点上运行了一些后台进程。(即使我退出了客户端，Visior服务也在运行)。

使用以下命令找到所有进程并将其终止

ps -ef | grep "ignite"
