goood

good job !

I got that:
{
"message": "Client request error: socket hang up",
"statusCode": 502,

}

mapping type has been removed in Es 6.x . See:https://www.elastic.co/guide/en/elasticsearch/reference/6.0/removal-of-types.html

for ES6.x, I use the follow

Since change in change in elasticsearch request for strict content-type checking , make sure to add header -H 'Content-Type: application/json' in your curl request. or you will get following error

{
  "error" : "Content-Type header [application/x-www-form-urlencoded] is not supported",
  "status" : 406
}

do add header -H 'Content-Type: application/json', then how to do with quote>

Elastic 6.x allows only one Type in Index, and version 7.x will completely remove Type.

Rejecting mapping update to [gb] as the final mapping would have more than 1 type: [tweet, user]

add header -H 'Content-Type:application/x-ndjson'. Content-Type is application/x-ndjson not application/json.

When sending requests to this endpoint the Content-Type header should be set to application/x-ndjson.
If you’re providing text file input to curl, you must use the --data-binary flag instead of plain -d. The latter doesn’t preserve newlines. Example:

$ cat requests
{ "index" : { "_index" : "test", "_type" : "_doc", "_id" : "1" } }
{ "field1" : "value1" }
$ curl -s -H "Content-Type: application/x-ndjson" -XPOST localhost:9200/_bulk --data-binary "@requests";

reference:Bulk Api

in es6.x, this is useful

curl -H 'Content-Type: application/json' -XPOST 'http://localhost:9200/_bulk?pretty' -d '

@zhengfeng-zhu
good job！it's working now

@alvesgabriel, I think you are now mixing up tweet and user. Following the advince of elastic, by default you split up different types in different indexes, so gb-user, gb-tweet, us-user, us-tweet, which results in:

POST /_bulk
{"create":{"_index":"us-user","_id":"1"}}
{"email":"john@smith.com","name":"John Smith","username":"@john"}
{"create":{"_index":"gb-user","_id":"2"}}
{"email":"mary@jones.com","name":"Mary Jones","username":"@mary"}
{"create":{"_index":"gb-tweet","_id":"3"}}
{"date":"2014-09-13","name":"Mary Jones","tweet":"Elasticsearch means full text search has never been so easy","user_id":2}
{"create":{"_index":"us-tweet","_id":"4"}}
{"date":"2014-09-14","name":"John Smith","tweet":"@mary it is not just text, it does everything","user_id":1}
{"create":{"_index":"gb-tweet","_id":"5"}}
{"date":"2014-09-15","name":"Mary Jones","tweet":"However did I manage before Elasticsearch?","user_id":2}
{"create":{"_index":"us-tweet","_id":"6"}}
{"date":"2014-09-16","name":"John Smith","tweet":"The Elasticsearch API is really easy to use","user_id":1}
{"create":{"_index":"gb-tweet","_id":"7"}}
{"date":"2014-09-17","name":"Mary Jones","tweet":"The Query DSL is really powerful and flexible","user_id":2}
{"create":{"_index":"us-tweet","_id":"8"}}

This is very easy to use

Elastic 6.x allows only one Type in Index, and version 7.x will completely remove Type.

It's cool,i remove type can run it...Maybe i need read document again

@maarten-kieft Comment has the best example for 7.x, copy paste in Kibana console works fine.

es returns error

{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Rejecting mapping update to [gb] as the final mapping would have more than 1 type: [user, tweet]"}],"type":"illegal_argument_exception","reason":"Rejecting mapping update to [gb] as the final mapping would have more than 1 type: [user, tweet]"},"status":400}

since 7.x ，one _index does not support multiple _type

these shells are @deprecated

@maarten-kieft, thanks !

@maarten-kieft thanks a lot for the example. Helped me a ton!
