elasticsearch 创建地图坐标索引问题

curl -X PUT 'localhost:9200/shops'  -d '{"mappings":{"_doc":{"properties":{"name":{"type":"text"},"location":{"type":"geo_point", "fielddata":{"format":"compressed","precision ":"1km"}},"total_type":{"type":"integer"},"total_id":{"type":"integer"},"other_info":{"type":"text"}}}}}' -H 'Content-type:application/json'
 
报错：{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"Mapping definition for [location] has unsupported parameters:  [fielddata : {precision=1km, format=compressed}]"}],"type":"mapper_parsing_exception","reason":"Failed to parse mapping [_doc]: Mapping definition for [location] has unsupported parameters:  [fielddata : {precision=1km, format=compressed}]","caused_by":{"type":"mapper_parsing_exception","reason":"Mapping definition for [location] has unsupported parameters:  [fielddata : {precision=1km, format=compressed}]"}},"status":400}

疑问： "fielddata":{"format":"compressed","precision":"1km"} 这个字段不是可以用吗？
