Prasanth Jayachandran commented on HIVE-13223:
----------------------------------------------
Throwing exception is going to fail these tests. I think the correct behaviour
is to throw exception for invalid files. To read rows out of ORC, first we need
to create Reader which reads footer, metadata, stripe information etc.. It is
at this phase we have to fail as we cannot read footers out of invalid files.
Only after successful creation of Reader we can create RecordReaders. If there
are no rows then hasNext() will return false immediately. We won't be able to
create RecordReaders with invalid files.
> HoS may hang for queries that run on 0 splits
