Elasticsearch + Oracle JDBC River

Question

也許這是一個簡單的問題，但在ElasticSearch即將推出。安裝了ES 1.4，Oracle 10g已啓動並運行，jdbc插件在ES中加載沒有問題。奇蹟還在努力..試圖建立一條河本聲明奇蹟/檢測：

---

PUT _river/mydata/_meta 
{ 
    "type": "jdbc", 
    "jdbc": { 
     "driver": "oracle.jdbc.OracleDriver", 
     "url": 「jdbc:oracle:thin:@host:1521:SID", 
     "user": 「oracleusr", 
     "password": 「 oraclepass", 
     "index": 「myindex", 
     "type": 「mytype", 
     "sql": "select * from aTable" 
     } 
}

，我得到這個錯誤的所有時間：

{ 
    "error": "MapperParsingException[failed to parse]; nested: ElasticsearchParseException[Failed to derive xcontent from (offset=0, length=323): [80, 85, 84, 32, 95, 114, 105, 118, 101, 114, 47, 109, 52, 99, 47, 95, 109, 101, 116, 97, 32, 10, 123, 10, 32, 32, 34, 116, 121, 112, 101, 34, 58, 32, 34, 106, 100, 98, 99, 34, 44, 10, 32, 32, 34, 106, 100, 98, 99, 34, 58, 32, 123, 10, 32, 32, 32, 32, 32, 32, 32, 32, 34, 100, 114, 105, 118, 101, 114, 34, 58, 32, 34, 111, 114, 97, 99, 108, 101, 46, 106, 100, 98, 99, 46, 79, 114, 97, 99, 108, 101, 68, 114, 105, 118, 101, 114, 34, 44, 10, 32, 32, 32, 32, 32, 32, 32, 32, 34, 117, 114, 108, 34, 58, 32, -30, -128, -100, 106, 100, 98, 99, 58, 111, 114, 97, 99, 108, 101, 58, 116, 104, 105, 110, 58, 64, 49, 48, 46, 49, 57, 52, 46, 49, 55, 46, 49, 55, 51, 58, 49, 53, 50, 49, 58, 109, 52, 99, 34, 44, 10, 32, 32, 32, 32, 32, 32, 32, 32, 34, 117, 115, 101, 114, 34, 58, 32, -30, -128, -100, 109, 52, 99, 34, 44, 10, 32, 32, 32, 32, 32, 32, 32, 32, 34, 112, 97, 115, 115, 119, 111, 114, 100, 34, 58, 32, -30, -128, -100, 32, 109, 52, 99, 49, 50, 48, 57, 48, 53, 34, 44, 10, 32, 32, 32, 32, 32, 32, 32, 32, 34, 105, 110, 100, 101, 120, 34, 58, 32, -30, -128, -100, 109, 52, 99, 34, 44, 10, 32, 32, 32, 32, 32, 32, 32, 32, 34, 116, 121, 112, 101, 34, 58, 32, -30, -128, -100, 112, 97, 105, 115, 34, 44, 10, 32, 32, 32, 32, 32, 32, 32, 32, 34, 115, 113, 108, 34, 58, 32, 34, 115, 101, 108, 101, 99, 116, 32, 42, 32, 102, 114, 111, 109, 32, 77, 52, 67, 80, 65, 73, 83, 34, 10, 32, 32, 32, 32, 32, 32, 125, 10, 125, 10]]; ", 
    "status": 400 
} 

的CLI我得到：

我首先雖然是一個連接公關但是檢查一下它似乎是一個與Oracle的映射有關的問題。有人已經完成了ES + Oracle River集成嗎？任何幫助將非常感激。

Answer 1

我發現了一個解決方案，它確實有效。而不是把命令對我所做的是有一個JSON配置文件是這樣的：

{ 
    "type" : "jdbc" , 
    "jdbc" :{ 
     "strategy" : "oneshot", 
     "driver" : "oracle.jdbc.OracleDriver", 
     "url" : "jdbc:oracle:thin:@host:1521:DNS", 
     "user" : "user", 
     "password" : "password", 
     "sql" : "select * from aTable", 
     "poll" : "1h", 
     "scale" : 0, 
     "autocommit" : false, 
     "fetchsize" : 100, 
     "max_rows" : 0, 
     "max_retries" : 3, 
     "max_retries_wait" : "10s" 
    }, 
    "index" : { 
     "index" : "aIndex", 
     "type" : "aType", 
     "bulk_size" : 100 
    } 
} 

，然後用這樣的捲曲稱之爲：

'http://127.0.0.1:9200/_river/jdbcriver/_meta' -d @config.json 

我不知道這是一個解析器問題或什麼，但這種方式像魅力一樣工作。

謝謝
