ES version : 2.4.4

We need Nested Query in our business , so I write code as ES doc says, but failed.  
My Doc Mapping coded as the following :  
------------------------ doc mapping --------------------------  
{  
"properties": {  
"name": {  
"type": "string",  
"analyzer": "ik"  
},  
"age": {  
"type": "integer"  
},  
"desc": {  
"type": "string",  
"analyzer": "ik"  
},  
"birthdate": {  
"type": "date",  
"format": "yyyy-MM-dd||yyyy-MM-dd HH:mm:ss"  
},  
"friends": {  
"type": "nested",  
"properties": {  
"name": {  
"type": "string",  
"analyzer": "ik"  
},  
"age": {  
"type": "integer"  
},  
"gender": {  
"type": "string",  
"index": "not\_analyzed"  
}  
}  
}  
}  
}

-------------------------- sample data ---------------------  
[

}  
]

I can index ( as well as query ) the doc data with other rest api client， but when I index the data with java api client, it goes wrong, the error message is : cant be changed from nested to Non nested 。

I have tried "dynamic : false/strict” to avoid changing field types, but still not work.

Anyone can figure it out ?

Many thanks !!!

Please format your code using `</>` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21). It will make your post more readable.

Or use markdown style like:

About "urgency" in the title, it's useless.

Read [this](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and specifically the "Also be patient" part.
