安装 Solr 4 后，我使用 DIH 进行了完全导入，但在错误日志中出现以下错误：

令我困惑的是这条线Unknown character set index for field '3687' received from server.。任何表中都没有字段3687！
我基本上是在设置一台新服务器并尝试从旧服务器迁移到该服务器。我使用 Puppet 配置了新服务器，并将所有数据库转移到新服务器上的 MySQL 数据库。
服务器是运行 MySQL 5.5.28-0ubuntu0.12.04.2、Tomcat 7.0.26、Solr 4.0.0.2012.08.06.22.50.47 的 Ubuntu 12.04。旧服务器是运行 MySQL 5.5.24 的 Ubuntu 12.04
知道完全导入出了什么问题吗？谢谢！
