出现这个情况的原因如下:

如果定义的缓存类型是REPLICATED模式，并且开启了持久化，后面将其改为PARTITIONED模式，并导入数据，后续重启的时候就会报这个错误。

比如下面这种情况：

default-config.xml

        <property name="cacheConfiguration">
            <list>
                <bean class="org.apache.ignite.configuration.CacheConfiguration">
                  ...
                    <property name="name" value="Test"/>
                    <property name="atomicityMode" value="ATOMIC"/>
                    <property name="cacheMode" value="REPLICATED"/>
                  ...
                </bean>
            </list>
        </property>

        ignite.destroyCache("Test");
        IgniteCache<Long, CommRate> cache = ignite.getOrCreateCache("Test");

当重新启动的时候，default-config.xml中的配置先生效，所以会出现这个问题。

解决办法就是在持久化模式下不要更改缓存模式，或者不要在配置文件中预定义缓存类型。

I can‘t reproduce your case. But the issue could occur if you had a REPLICATED cache and after some time changed it to PARTITIONED and for example call to getOrCreateCache keeping old cache name.
