How to create mapping with json file in elasticsearch2.3?

Question

I'm using ES2.3

create new index mapping with below command works.

curl -XPUT 'http://localhost:9200/megacorp' -d '
{
    "settings": {
        "number_of_shards": 3,
        "number_of_replicas": 1
    }, 
    "mappings": {
        "employee": {
            "properties": {
                "first_name": {
                    "type": "string"
                }, 
                "last_name": {
                    "type": "string"
                }, 
                "age": {
                    "type": "integer"
                }, 
                "about": {
                    "type": "string"
                }, 
                "interests": {
                    "type": "string"
                }, 
                "join_time": {
                    "type": "date", 
                    "format": "dateOptionalTime", 
                    "index": "not_analyzed"
                }
            }
        }
    }
}
'

now i hope can use a json file to create same index. tmap.json file like below

    {
    "settings": {
        "number_of_shards": 3,
        "number_of_replicas": 1
    }, 
    "mappings": {
        "employee": {
            "properties": {
                "first_name": {
                    "type": "string"
                }, 
                "last_name": {
                    "type": "string"
                }, 
                "age": {
                    "type": "integer"
                }, 
                "about": {
                    "type": "string"
                }, 
                "interests": {
                    "type": "string"
                }, 
                "join_time": {
                    "type": "date", 
                    "format": "dateOptionalTime", 
                    "index": "not_analyzed"
                }
            }
        }
    },
    "aliases": [ "source" ]
  }

then i usr curl to create it.

curl -s -XPOST 'localhost:9200/megacorp' --data-binary @tmap.json

and

curl -XPUT 'http://localhost:9200/megacorp' -d @tmap.json

both above commands not working, get error like below.

{"error":{"root_cause":[{"type":"class_cast_exception","reason":"java.util.ArrayList cannot be cast to java.util.Map"}],"type":"class_cast_exception","reason":"java.util.ArrayList cannot be cast to java.util.Map"},"status":500}%

how to create index with curl and my json file? this is really confused me for long time.

can any body help me? thanks.

The way you define alias is wrong. It should be a map instead of an array.

  {
    "settings": {
        "number_of_shards": 3,
        "number_of_replicas": 1
    }, 
    "mappings": {
        "employee": {
            "properties": {
                "first_name": {
                    "type": "string"
                }, 
                "last_name": {
                    "type": "string"
                }, 
                "age": {
                    "type": "integer"
                }, 
                "about": {
                    "type": "string"
                }, 
                "interests": {
                    "type": "string"
                }, 
                "join_time": {
                    "type": "date", 
                    "format": "dateOptionalTime", 
                    "index": "not_analyzed"
                }
            }
        }
    },
    "aliases": { "source": {} }
  }

i got it, thanks. other question, how to storage template file in config/templates folder, do you know it?

philipskokoh Over a year ago

I do not understand your question. What do you mean by template file? I don't think Elasticsearch has something called template file.

user670809 Over a year ago

thanks for your help. I found it from ES version 2.0 or newer will not supported for template files storage in local file, you have to use curl -XPUT localhost:9200/_template/xxx -d '{}' for your template. other will would be possible you storage it on local folder then run command by handle , like curl -XPUT localhost:9200/_template/xxx -d @templatefile
