current support/non-support for empty JSON files mixed in with regular JSON files

[Daniel Barclay <db...@maprtech.com>]

Do we intend/expect Drill to _currently_ handle having empty (zero-byte)
JSON files mixed in with regular JSON files?


The in-progress fix for DRILL-2288 hits problems with some cases of
having empty JSON files mixed in with some non-empty JSON files.

However, it's not clear whether those cases are currently supported
(and DRILL-2288 changes need to not break that support) or those cases
are not supported yet anyway, so changes needed to fix DRILL-2288 don't
need to leave Drill in the state of handling such empty JSON files.

Thanks,
Daniel
