I suspect this might be related to having 0 row files in the buckets not
having any recorded schema.

You can also experiment with hive.optimize.index.filter=false, to see if
the zero row case is artificially produced via predicate push-down.


That shouldn't be a problem unless you've turned on
hive.orc.splits.include.file.footer=true (recommended to be false).

Your row-locations don't actually match any Apache source jar in my
builds, are there any other patches to consider?

Cheers,
Gopal
