Prasanth Jayachandran commented on HIVE-13223:
----------------------------------------------
For text formats, this makes sense as we don't have to read any footer/metadata
to read rows out of it. Hence 0 length files can be handled just be returning
false in hasNext(). But I don't think it's valid for row columnar formats that
reads MAGIC bytes/footers etc..
> HoS may hang for queries that run on 0 splits
