Elasticsearch Java API prepareIndex overwrites existing mapping

I'm in trouble with the overwriting action of prepareIndex method in Elasticsearch Java API.

The problem is that my mapping definition has changed after new document has indexed.

First of all, I defined an mapping to set "not_analyzed" index for a particular field.

String json = myMethodToGetMapping();
PutMappingResponse pmrs = client.admin().indices().preparePutMapping("my_index").setType("my_type").setSource(json).setIgnoreConflicts(true).execute().actionGet();

if (pmrs == null || !pmrs.isAcknowledged()) {
    System.out.println("Put Mapping Failure.");
} else {
    System.out.println("Put Mapping Success.");
}

In my mapping string(json), there is a field has settings like below.

"myFieldExact":{
    "type":"string",
    "index": "not_analyzed",
    "dynamic": false
}

After the code has executed, I could see the proper mapping which I want to get.

curl -XGET http://{my_ip_address}:9200/my_index/my_type/_mapping/

{"my_type":{"properties":{........ "myFieldExact":{"type":"string","index":"not_analyzed","omit_norms":true,"index_options":"docs"},...... }}}

HOWEVER, this mapping has been changed after I put some data using Java API prepareIndex.

MyObject myObject = new MyObject();
myObject.setMyFieldExact("some-value");
String json = new org.codehaus.jackson.map.ObjectMapper().writeValueAsString(myObject);
client.prepareIndex("my_index", "my_type", "my_id")
            .setSource(json).execute().actionGet();

The document successfully indexed into "my_index/my_type/my_id".

Here is the problem I have.

After the new record has been indexed, the original mapping definition has changed like below.

curl -XGET http://{my_ip_address}:9200/my_index/my_type/_mapping/

{"my_type":{"properties":{........ "myFieldExact":{"type":"string"},...... }}}

In short, the "index":"not_analyzed" property has been gone after the new document has indexed.

Is there anyone can help me?

Thank you very much in advance.
