我试图在Elasticsearch中对一个值进行geomap,但是client_location
的值类型被设置为一个字符串,我想将它更改为geo_point
。当我运行以下命令时,我得到了以下信息:
#curl -XGET "http://core.z0z0.tk:9200/_all/_mappings/http?pretty"
{
"packetbeat-2015.12.04" : {
"mappings" : {
"http" : {
"properties" : {
"@timestamp" : {
"type" : "date",
"format" : "strict_date_optional_time||epoch_millis"
},
"beat" : {
"properties" : {
"hostname" : {
"type" : "string"
},
"name" : {
"type" : "string"
}
}
},
"bytes_in" : {
"type" : "long"
},
"bytes_out" : {
"type" : "long"
},
"client_ip" : {
"type" : "string"
},
"client_location" : {
"type" : "string"
},
"client_port" : {
"type" : "long"
},
"client_proc" : {
"type" : "string"
},
"client_server" : {
"type" : "string"
},
"count" : {
"type" : "long"
},
"direction" : {
"type" : "string"
},
"http" : {
"properties" : {
"code" : {
"type" : "long"
},
"content_length" : {
"type" : "long"
},
"phrase" : {
"type" : "string"
}
}
},
"ip" : {
"type" : "string"
},
"method" : {
"type" : "string"
},
"notes" : {
"type" : "string"
},
"params" : {
"type" : "string"
},
"path" : {
"type" : "string"
},
"port" : {
"type" : "long"
},
"proc" : {
"type" : "string"
},
"query" : {
"type" : "string"
},
"responsetime" : {
"type" : "long"
},
"server" : {
"type" : "string"
},
"status" : {
"type" : "string"
},
"type" : {
"type" : "string"
}
}
}
}
}
}
当我运行以下命令将值的类型从string更改为geo_point
时,将得到以下错误:
# curl -XPUT "http://localhost:9200/_all/_mappings/http" -d '
> {
> "http" : {
> "properties" : {
> "client_location" : {
> "type" : "geo_point"
> }
> }
> }
> }
> '
{"error":{"root_cause":[{"type":"merge_mapping_exception","reason":"Merge failed with failures {[mapper [client_location] of different type, current_type [string], merged_type[geo_point]]}"}],"type":"merge_mapping_exception","reason":"Merge failed with failures {[mapper [client_location] of different type, current_type [string], merged_type [geo_point]]}"},"status":400}
有什么建议,我应该如何正确地改变类型?
提前谢谢。

不幸的是,一旦创建了一个字段,就不能再改变它的类型了。最好的做法是删除索引并通过适当的映射正确地重新创建它。
如果不想立即删除索引,另一个临时解决方案是在现有字段中创建一个子字段:
# curl -XPUT "http://localhost:9200/_all/_mappings/http" -d '{
"http": {
"properties": {
"client_location": {
"type": "string",
"fields": {
"geo": {
"type": "geo_point"
}
}
}
}
}
}'
然后,您可以使用client_location.geo
在查询中访问它。请注意,您必须重新索引您的数据,以填充新的子字段.这意味着您也可以删除索引并正确地重新创建它。

在安装Packet节拍之后,您需要确保自己安装packet节拍模板,如下所述(即它不是自动完成的):https://www.elastic.co/guide/en/beats/packetbeat/current/packetbeat-getting-started.html#packetbeat-template
curl -XPUT 'http://localhost:9200/_template/packetbeat' -d@/etc/packetbeat/packetbeat.template.json
