mysql - Jdbc river 在 MapperParsingException 上停止

Question

我使用的是 Elasticsearch 版本 1.2.0，Jdbc river 版本 1.2.0.1。

以下是我的Jdbc river命令。

curl -XPUT 'localhost:9200/_river/tbl_messages/_meta' -d '{
    "type" : "jdbc",
    "jdbc" : {
    "strategy" : "simple",
    "url" : "jdbc:mysql://localhost:3306/messageDB",
    "user" : "username",
    "password" : "password",
    "sql" : "select messageAlias.id as _id,messageAlias.subject as subject from tbl_messages messageAlias",
    "index" : "MessageDb",
    "type" : "tbl_messages", 
    "maxbulkactions":1000,
    "maxconcurrentbulkactions" : 4,
    "autocommit" : true,
    "schedule" : "0 0-59 0-23 ? * *"    
    }
}'

主题列的索引元数据

subject: {
    type: string
}

此表有 200 万条记录，主题字段包含任意字符串。一些示例数据是“你被邀请了”、“{New York:45} We rock!!”、“{Invitation:27}”等等。

我的问题是，当 jdbc river 遇到这样一 strip 有 {anything inside of this} 的记录时，它会停止 river 并抛出解析异常。它永远不会继续索引下一条记录。

删除db中的这条记录，清除ES_HOME/data中的数据，重新创建河流似乎是唯一的方法，直到再次遇到上述格式化的记录。

如何在解析少量记录时不考虑异常继续索引？

Answer 1

它与 Elasticsearch 有关，与河流无关。
