Elasticsearch + Oracle JDBC River

Question

也许这是一个简单的问题，但我是 ElasticSearch 的新手。安装 es 1.4，Oracle 10g 已启动并运行，在 ES 中加载 jdbc 插件没有问题。 Marvel 也在工作.. 尝试在 Marvel/Sense 中使用此语句创建一条河流：

---

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"
      }
}

---

我一直收到这个错误：

{
   "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
}

在 CLI 上我得到：

    at org.elasticsearch.index.mapper.DocumentMapper.parse(DocumentMapper.java:562)
    at org.elasticsearch.index.mapper.DocumentMapper.parse(DocumentMapper.java:490)

我首先虽然是连接问题，但检查它似乎是 ES 和 Oracle 中的映射问题。有人做过 ES+Oracle River 集成吗？任何帮助将不胜感激。

Answer 1

我找到了一个非常直接的解决方案。而不是把命令放在我所做的是有一个像这样的 json 配置文件：

{
    "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
    }
}

然后像这样用 curl 调用它：

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

我不知道这是解析器问题还是什么，但这种方式就像一种魅力。

谢谢
