I came across this issue today, setting upsert: true while making a bulk create request tries to call create on a potentially already existing record giving:

  "_index": "index_name",
  "_type": "type_name",
  "_id": "2276654",
  "status": 409,
  "error": {
    "type": "version_conflict_engine_exception",
    "reason": "[type_name][2276654]: version conflict, document already exists (current version [4])",
    "index_uuid": "149AMdPPTHSo4LvC_bBrkw",
    "shard": "4",
    "index": "index_name"
  }
}

I created a small PR for this - can anyone help test
