Przemysław Szeremiota commented on SOLR-12094:
----------------------------------------------

Thank you Dawid for fixing my poor issue formatting.

Yes, it is a bug: visibility of root fields in output depends on their order 
within input document, so functionally indifferent JSON with "exams" as a first 
field would have all root-level fields skipped from resulting document.

> JsonRecordReader ignores root fields after split

> JsonRecordReader, when configured with other than top-level split, ignores 
> all top-level JSON nodes after split ends, for example:
> {code}
> {
>   "first": "John",
>   "last": "Doe",
>   "grade": 8,
>   "exams": [
>     {
>         "subject": "Maths",
>         "test": "term1",
>         "marks": 90
>     },
>     {
>         "subject": "Biology",
>         "test": "term1",
>         "marks": 86
>     }
>   ],
>   "after": "456"
> }
> {code}
> Node "after" won't be visible in SolrInputDocument constructed from 
> /update/json/docs.
> I don't have fix, only (breaking) patch for relevant test
