Mapping:

PUT /my_index/_mapping/blogpost
{
  "properties": {
    "user": {
      "properties": {
        "name": { 
          "type": "string",
          "fields": {
            "raw": { 
              "type":  "string",
              "index": "not_analyzed"
            }
          }
        }
      }
    }
  }
}

Error:

{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "mapper [user] of different type, current_type [long], merged_type [ObjectMapper]"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "mapper [user] of different type, current_type [long], merged_type [ObjectMapper]"
  },
  "status": 400
}

Data to be ingested:

PUT /my_index/blogpost/2
{
  "title": "Relationships",
  "body": "It's complicated...",
  "user": {
    "id": 1,
    "name": "John Smith"
  }
}

How should I resolve this mapping Issue?

It seems you have indexed the user field as a long somewhere. you need to reindex your data to fix it. Take a look at the reindex API how to index your data into another index, where you can fix the mapping beforehand.
