出現這個情況的原因如下:

如果定義的緩衝類型是REPLICATED模式，並且開啟了持久化，後面將其改為PARTITIONED模式，並匯入資料，後續重啟的時候就會報這個錯誤。

比如下面這種情況：

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");

當重新啟動的時候，default-config.xml中的配置先生效，所以會出現這個問題。

解決辦法就是在持久化模式下不要更改緩衝模式，或者不要在設定檔中預定義緩衝類型。

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.
