I want to import a sub-document of join type, but the official document does not give an example. The sub-document needs to set name and parame and specify roting.  
"my\_join\_field": {  
"name": "answer",  
"parent": "1"  
}  
How to set these two parameters?  
Can you give an example of EsSparkSQL. saveToEs?
