我最近一直在使用带有 MySQL 的 elasticsearch，没有任何问题。我的服务器最近从 MySQL 迁移到 MariaDB，现在 JDBC 河流似乎甚至被最基本的同步冻结了。有谁知道他们是否兼容？

这是一个示例代码：

PUT /_river/my_jdbc_river/_meta
{
    "type" : "jdbc",
    "jdbc" : {
        "url" : "jdbc:mysql://HOST/DATABASE",
        "user": "username",
        "password": "password",
        "sql" : "select * from table"
    }
}

它只是挂在以下内容上：

[2014-05-19 16:11:49,080][INFO ][cluster.metadata         ] [Wade Wilson] [_river] update_mapping [my_jdbc_river] (dynamic)

下载 MariaDB 的“连接器”：

在 https://downloads.mariadb.org/client-java/1.1/下载mariadb-java-client-1.1.7.jar

他们将 mariadb-java-client-1.1.7.jar 移动到 /your_path_to_elasticsearch/plugins 中，如下所示：

> [root@SpaceConnection elasticsearch-1.3.4]# ll plugins/jdbc/
> -rw-r--r-- 1 root root 280826 Oct 16 22:03 elasticsearch-river-jdbc-1.3.4.0.jar
> -rw-r--r-- 1 root root    380 Oct 16 22:03 log4j2.xml
> -rw-r--r-- 1 root root    234 Oct 16 22:03 log4j.properties
> -rw-r--r-- 1 root root 230704 Mar 29  2014 mariadb-java-client-1.1.7.jar

然后运行 ​​bin/elasticsearch

当然，你必须在https://github.com/jprante/elasticsearch-river-jdbc#how-to-start-the-jdbc-river一步一步安装之前
