Elasticsearch add mapping to existing index

[alexus]

I'm stumble upon Changing Mapping with Zero Downtime | Elastic blog post, however it's dated back in 2013.

I need to add mapping to existing index, what is the best way to approach this?

Thanks in advance.

Refer to the documentation here on the PUT mapping API:

I guess, I'm doing something wrong, can't put my finger on it...

delete index:

$ curl -XDELETE 0:9200/test?pretty
{
  "acknowledged" : true
}
$ 

create index:

$ curl -XPUT 0:9200/test?pretty
{
  "acknowledged" : true,
  "shards_acknowledged" : true
}
$

create dummy document:

$ curl -XPOST 0:9200/test/t?pretty -d '{ "price": 1 }'
{
  "_index" : "test",
  "_type" : "t",
  "_id" : "AVi7cocPMoL1V0O0z0Lk",
  "_version" : 1,
  "result" : "created",
  "_shards" : {
    "total" : 2,
    "successful" : 1,
    "failed" : 0
  },
  "created" : true
}
$

get existing mapping:

$ curl -XGET 0:9200/test/_mapping?pretty
{
  "test" : {
    "mappings" : {
      "t" : {
        "properties" : {
          "price" : {
            "type" : "long"
          }
        }
      }
    }
  }
}
$ 

putting mapping:

$ curl -XPUT 0:9200/test/_mapping/t?pretty -d '
{
  "test" : {
    "mappings" : {
      "t" : {
        "properties" : {
          "price": {
            "type": "integer"
          }
        }
      }
    }
  }
}
'
{
  "error" : {
    "root_cause" : [
      {
        "type" : "mapper_parsing_exception",
        "reason" : "Root mapping definition has unsupported parameters:  [test : {mappings={t={properties={price={type=integer}}}}}]"
      }
    ],
    "type" : "mapper_parsing_exception",
    "reason" : "Root mapping definition has unsupported parameters:  [test : {mappings={t={properties={price={type=integer}}}}}]"
  },
  "status" : 400
}
$ 

Please advice.
