我正在使用的示例来自： http ://blog.knoldus.com/2014/06/22/playing-kundera-cassandra/

我正在玩！2.4.6 框架与 Cassandra 2.2。不允许连接到数据库的项目可能有什么问题？我是否需要对 CQL 或 Kundera 版本进行一些更改，以便我的数据库可以连接？我的 persistence.xml 文件如下：

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
    https://raw.github.com/impetus-opensource/Kundera/Kundera-2.0.4/kundera-core/src/test/resources/META-INF/persistence_2_0.xsd"
    version="2.0">

    <persistence-unit name="cassandra_employees">
        <provider>com.impetus.kundera.KunderaPersistence</provider>
        <class>models.domains.Employee</class>
        <properties>
            <property name="kundera.nodes" value="localhost" />
            <property name="kundera.port" value="9042" />
            <property name="kundera.keyspace" value="EmployeeExample" />
            <property name="kundera.dialect" value="cassandra" />
            <property name="kundera.client.lookup.class" value="com.impetus.client.cassandra.thrift.ThriftClientFactory" />
            <property name="kundera.cache.provider.class" value="com.impetus.kundera.cache.ehcache.EhCacheProvider" />
            <property name="kundera.cache.config.resource" value="/ehcache-test.xml" />
        </properties>
    </persistence-unit>

</persistence>

请告诉我是否必须对 Cassandra 或 CQL 进行一些与版本相关的更改，以及在哪个文件中？

在配置下使用，它在我的系统上运行良好..

更新 cassandra.yaml:
FROM: start_rpc: false
TO: start_rpc: true

Persistence.xml：
下面提到的单元名称是随机的，将用于访问这个特定的持久性。
keyspace name 是在 cassandra 中创建的表的名称。 

<persistence-unit name="persistence">
        <provider>com.impetus.kundera.KunderaPersistence</provider>
        <properties>
            <property name="kundera.nodes" value="localhost" />
            <property name="kundera.port" value="9160" />
            <property name="kundera.keyspace" value="trial1" />
            <property name="kundera.dialect" value="cassandra" />
                <property name="kundera.client.lookup.class" value="com.impetus.client.cassandra.thrift.ThriftClientFactory" />

            <property name="kundera.pool.size.max.active" value="500" />
            <property name="kundera.pool.size.max.total" value="500" />
        </properties>
