[WARN][plugins] plugin jdbc- river，调用自定义 onModule 方法失败

Question

我已经安装了 Elasticsearch 1.7.1 版本。它工作正常。我也安装了 JDBC 驱动程序。检查下面我的插件文件夹

E:\Xampp\htdocs\my-elastic\elasticsearch-1.7.1\plugins\river-jdbc

的目录

09-09-2015  19:19            66,891 elasticsearch-river-jdbc-2.3.1.jar
27-07-2015  15:55           959,984 mysql-connector-java-5.1.33.jar

所以我的连接器文件在插件文件夹中。当我启动 elasticsearch 时，它会显示警告错误，如下所示。

我该如何解决这个问题。请帮助解决问题。

提前致谢

Answer 1

根据 JDBC plugin's documentation，你应该使用 ES 1.7 的版本是 1.7.0.1。

所以再次尝试使用 1.7.0.1 包安装您的插件 http://xbib.org/repository/org/xbib/elasticsearch/importer/elasticsearch-jdbc/1.7.0.1/elasticsearch-jdbc-1.7.0.1-dist.zip

然后关注这些installations steps

更新

实际上，我没听懂你在尝试安装 river 插件。自 rivers have been deprecated, the JDBC importer does not provide a river plugin anymore since version 1.5. If you absolutely want to use the river plugin, you need at most ES 1.5 (i.e. it won't work with ES 1.6+) and the JDBC plugin v1.5.

如果您决定沿着这条路走下去，您可以使用

安装 JDBC river 插件

./bin/plugin --install jdbc --url http://xbib.org/repository/org/xbib/elasticsearch/plugin/elasticsearch-river-jdbc/1.5.0.4/elasticsearch-river-jdbc-1.5.0.4.zip

如果您决定继续使用 ES 1.7，那么您可以运行 JDBC 导入器作为一个独立的工具，方法是运行在 bin文件夹

[WARN][plugins] plugin jdbc- river，调用自定义 onModule 方法失败

[WARN ][plugins] plugin jdbc- river, failed to invoke custom onModule method

java

mysql

jdbc

elasticsearch
