我正在尝试使用 org.elasticsearch.hadoop.pig.EsStorage (2.2.0) 通过 pig 将 geoshape（如下所示）存储到 ES：

{
    "location" : {
        "type" : "circle",
        "coordinates" : [-45.0, 45.0],
        "radius" : "100m"
    }
}

或者 ：

{
    "location" : {
        "type" : "polygon",
        "orientation" : "clockwise",
        "coordinates" : [
            [ [-177.0, 10.0], [176.0, 15.0], [172.0, 0.0], [176.0, -15.0], [-177.0, -10.0], [-177.0, 10.0] ],
            [ [178.2, 8.2], [-178.8, 8.2], [-180.8, -8.8], [178.2, 8.8] ]
        ]
    }
}

我们尝试了以下方法：

REGISTER ./elasticsearch-hadoop-2.2.0.jar;

loadedRecords = LOAD 'inputFile.csv' USING PigStorage('|') AS (type:chararray,coordinates:bag{(float,float)},radius:chararray);

elasticData = foreach loadedRecords GENERATE (type ,{(45.0f,46.0f)},radius) AS geoArea:tuple(type:chararray,coordinates:bag{(float,float)},radius:chararray);

DESCRIBE elasticData ;

DUMP elasticData;

STORE elasticData INTO 'myindex/mytype' USING org.elasticsearch.hadoop.pig.EsStorage('es.http.retries=10','es.nodes=localhost','es.index.auto.create=true','es.mapping.pig.tuple.use.field.names=false');

并在解析坐标时收到错误，遇到非数值并失败。（类型被解析为 CIRCLE）

我们还尝试了以下方法：

我尝试了另一件事，但这也有问题：

REGISTER ./elasticsearch-hadoop-2.2.0.jar;

loadedRecords = LOAD 'inputFile.csv' USING PigStorage('|') AS (type:chararray,coordinates:chararray,radius:chararray);

--elasticData = foreach loadedRecords GENERATE (type ,{(45.0f,46.0f)} ,radius) AS geo:tuple(type:chararray,coordinates:bag{(float,float)},radius:chararray;
elasticData = foreach loadedRecords GENERATE TOMAP('type','circle','coordinates','[40.0f,46.0f]','radius','150m') AS geo:map[chararray];
DESCRIBE elasticData ;

DUMP elasticData;

STORE elasticData INTO 'myindex/mytype' USING org.elasticsearch.hadoop.pig.EsStorage('es.http.retries=10','es.nodes=host','es.index.auto.create=true','es.mapping.pig.tuple.use.field.names=false');

有人使用 pig 将 geoshape 存储到 ES 并可以帮助我们吗？

谢谢！

你能显示这个索引的映射吗？前段时间我在 Pig 中遇到了类似的坐标问题——我所做的是：

  1. 在 ES 模式中，我定义了位置

    "location": {   
      "type": "geo_point"   
}

  2. 生成的位置为 TOTUPLE(longitude,latitude)

希望能帮助到你。
