When a field is not mapped, Elasticsearch tries to generate a mapping update
from the parsed document. Some documents can introduce corner-cases, for
instance in the event of a multi-valued field whose values would be mapped to
different field types if they were supplied on their own, see for instance:
```
PUT index/doc/1
{
"foo": ["2017-11-10T02:00:01.247Z","bar"]
}
```
In that case, dynamic mappings want to map the first value as a `date` field
and the second one as a `text` field. This currently throws an exception,
which is expected, but the wrong one since it throws a `class_cast_exception`
(which triggers a HTTP 5xx code) when it should throw an
`illegal_argument_exception` (HTTP 4xx).

@jpountz exactly which 4xx error will this wind up returning? |

@andrewvc A generic illegal argument exception is treated as a generic bad request so 400. |

@jasontedor hmmm, so that means these events are un-indexable (LS will send them to the DLQ). That seems right to me. |
