Creating a mapping for an existing index with a new type in elasticsearch

Question

I found an article on elasticsearch's site describing how to 'reindex without downtime', but that's not really acceptable every time a new element is introduced that needs to have a custom mapping (http://www.elasticsearch.org/blog/changing-mapping-with-zero-downtime/)

Does anyone know why I can't create a mapping for an existing index but a new type in elasticsearch? The type doesn't exist yet, so why not? Maybe I'm missing something and it IS possible? If so, how can that be achieved?

Thanks, Vladimir

What have you tried to do? and what's not working? You can always create new type (with its own mapping) — progrrammer
That's the point -- I don't think I can create a new type with its own mappings. Any time I try I get the following error: { "error": "IndexAlreadyExistsException[[tluseravailability] already exists]", "status": 400 } — Vladimir
I think I know what are you doing, I want to verify, Can you write the json you are using to add mapping for the type? — progrrammer
Here it is: { "mappings" : { "test" : { "properties" : { "test1" : { "type" : "string", "index" : "not_analyzed" }, "test2" : { "type" : "string", "index" : "not_analyzed" } } } } } — Vladimir
So, it is new type you want to create? what's mapping you used to create index? — progrrammer

Here is a simple example to create two type mapping in a index, (one after another)

I've used i1 as index and t1 and t2 as types,

Create index
```
curl -XPUT "http://localhost:9200/i1"
```

Create type 1

curl -XPUT "http://localhost:9200/i1/t1/_mapping" -d
{
   "t1": {
      "properties": {
         "field1": {
            "type": "string"
         },
         "field2": {
            "type": "string"
         }
      }
   }
}'

Create type 2

curl -XPUT "localhost:9200/i1/t2/_mapping" -d'
{
   "t2": {
      "properties": {
         "field3": {
            "type": "string"
         },
         "field4": {
            "type": "string"
         }
      }
   }
}'

Now Looking at mapping( curl -XGET "http://localhost:9200/i1/_mapping" ), It seems like it is working.

Hope this helps!! Thanks
