voltdb是企业版5.1.2
Kafka是2.9.2-0.8.1.1，也尝试了2.10-0.8.2.1
沃尔特DB报192.168.56.101
Kafka报192.168.56.102
以下是我对voltdb的部署配置：

<deployment>
  <cluster hostcount="1" sitesperhost="4" kfactor="0" />

  <commandlog enabled="true">
    <frequency time="400" transactions="1000"  />
  </commandlog>

  <export>
    <configuration enabled="true" type="kafka" stream="archive">
      <property name="metadata.broker.list">192.168.56.102:9092</property>
      <property name="producer.type">sync</property>
      <property name="batch.mode">true</property>
    </configuration>
  </export>
</deployment>

架构定义为：

drop table person if exists;
create table person (
  ic varchar(9) not null,
  first_name varchar(20) not null,
  last_name varchar(20) not null,
  middle_name varchar(20),
  gender tinyint not null,
  dob timestamp not null,
  date_created timestamp default now
);
partition table person on column ic;

export table person to stream archive;

对于kafka的server.properties，我只添加了这一行

auto.create.topics.enable=true

我首先开始Kafka如下：

bin/zookeeper-server-startsh config/zookeeper.properties
bin/kafka-server-start.sh config/server.properties

当我启动voltdb时，我遇到了以下异常：

david@u14voltdb:~$ voltdb create catalog.jar --deployment=config.xml

在Kafka那边，我一直在想：

[2015-05-14 00:40:08,197] INFO Closing socket connection to /192.168.56.101. (kafka.network.Processor)

有什么建议吗？
