Elasticsearch 2.x plugin 问题汇总

1、Elasticsearch 2.3.2 jdbc 插件，在执行oracle的脚本时，报错没有可用的驱动

[00:18:00,518][ERROR][importer.jdbc.source.standard][pool-3-thread-1] while opening read connection: jdbc:oracle:thin:@//10.10.100.42:1521/gjcrm No suitable driver found for jdbc:oracle:thin:@//10.10.100.42:1521/gjcrm
java.sql.SQLException: No suitable driver found for jdbc:oracle:thin:@//10.10.100.42:1521/gjcrm
        at java.sql.DriverManager.getConnection(DriverManager.java:689) ~[?:1.8.0_101]
        at java.sql.DriverManager.getConnection(DriverManager.java:208) ~[?:1.8.0_101]

    发现oracle自带的驱动无法使用,在官网上下载了ojdbc6.jar才行。

 

2、Elasticsearch 2.3.2 sql 插件

    执行后报错：

Error: {"error":{"root_cause":[{"type":"invalid_index_name_exception","reason":"Invalid index name [_sql], must not start with '_'","index":"_sql"}],"type":"invalid_index_name_exception","reason":"Invalid index name [_sql], must not start with '_'","index":"_sql"},"status":400}

 原因是添加插件后没重启elasticsearch，重启即可
