Szehon Ho commented on HIVE-13223:
----------------------------------
We can of course ask, and of course hanging is not a good behavior, but Spark
community might consider a job with 0 splits as invalid. It has always been
not so-great behavior on Hive side to have empty files in buckets (I guess
HIVE-12638 is a similar complaint).
Just to explore the options, is there any JIRA tracking ORC-side fix for handle
0-length files?
