If you really deleted the index, the mapping in this index should not exist anymore.
Do you have any other index in your cluster with a similar type name?

To answer to the question: <code>How to delete document types in elasticsearch?</code>, use <a href="http://www.elasticsearch.org/guide/reference/api/admin-indices-delete-mapping/" rel="noreferrer">Delete Mapping API</a>:

<pre><code>curl -XDELETE http://localhost:9200/index/type
</code></pre>

EDIT: From elasticsearch 2.0, it won't be possible anymore. See <a href="https://www.elastic.co/guide/en/elasticsearch/plugins/2.0/plugins-delete-by-query.html" rel="noreferrer">Mapping changes</a>. You will have to install the <a href="https://www.elastic.co/guide/en/elasticsearch/plugins/current/plugins-delete-by-query.html" rel="noreferrer">Delete By Query plugin</a> and run a query which will remove your documents but the mapping will still exist. So it will most likely better to reindex your documents in another index without the old type.

But as @mguillemin and @javanna said, when you delete an index, every mapping attached to this index is deleted as well:

<pre><code>curl -XDELETE http://localhost:9200/index
</code></pre>

blocks|key|1472469|text|在最新版本的elastic+search中，不再支持删除文档类型。它在documentation中提到过|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1472470|1472471|不再可以删除某个类型的映射。相反，您应该删除索引并使用新的映射重新创建它。|blockquote|1472472|1472473|entityMap|0|LINK|mutability|MUTABLE|url|https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-delete-mapping.html^0|Z|D|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@$A|R|B|S|1|T]]|C|$]]|$1|D|3|-4|5|6|7|U|8|@]|9|@]|C|$]]|$1|E|3|F|5|G|7|V|8|@]|9|@]|C|$]]|$1|H|3|-4|5|6|7|W|8|@]|9|@]|C|$]]|$1|I|3|-4|5|6|7|X|8|@]|9|@]|C|$]]]|J|$K|$5|L|M|N|C|$O|P]]]]

In the latest version of elastic search, they no longer support deleting document types. It's mentioned in the <a href="https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-delete-mapping.html" rel="nofollow noreferrer">documentation</a>

<blockquote>
 It is no longer possible to delete the mapping for a type. Instead you
 should delete the index and recreate it with the new mappings.

You can use <code>_delete_by_query</code> path to delete type.

<pre><code>POST index-name/type-name/_delete_by_query
{
 "query": { 
 "match": {
 "message": "some message"
 }
 }
}
</code></pre>

I create an index "myindex" with a specified document type "mytype". I am able to delete the index, but it appears that "mytype" still exists without being tied to the index. 

How do I get rid of "mytype"?

我创建了一个具有指定文档类型"mytype“的索引"myindex”。我可以删除索引，但看起来"mytype“仍然存在，没有绑定到索引。如何去掉"mytype"？
