I also got an error during reindex.

```
{
        "index": "master_index",
        "type": "wineventlog",
        "id": "AV3ApkZWIViJrh4V7OBM",
        "cause": {
            "type": "illegal_argument_exception",
            "reason": "mapper [process_id] cannot be changed from type [text] to [long]"
        },
        "status": 400
    },
```
