我正在使用springboot创建一个web服务，并希望在hbase中持久化我的数据模型。我想用昆德拉来完成这个任务。但是，我不能让它工作。当启动应用程序时，它会启动、冻结大约一分钟并进入超时状态。以下是我的一些配置片段：
my persistence.xml:

<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
    http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0">
    <persistence-unit name="hbase_pu">
        <provider>com.impetus.kundera.KunderaPersistence</provider>     
        <properties>            
            <property name="kundera.nodes" value="my-hbase-server.example.com"/>
            <property name="kundera.port" value="2181"/>
            <property name="kundera.keyspace" value="mykeyspace"/>
            <property name="kundera.dialect" value="hbase"/>
            <property name="kundera.client.lookup.class" value="com.impetus.client.hbase.HBaseClientFactory" />
            <property name="kundera.ddl.auto.prepare" value="update"/>             
        </properties>       
    </persistence-unit>
</persistence>

实体管理器的配置：

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    final LocalContainerEntityManagerFactoryBean bean = new LocalContainerEntityManagerFactoryBean();
    return bean;
}

当你试着运行这个程序的时候，它看起来很正常：

... many info outputs ...

然后，它冻结了大约一分钟，之后，它崩溃了：

这里出了什么问题？我错过了什么吗？如果是的话，是什么？
