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

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": {} }
}
