Owen O'Malley commented on HIVE-8732:
-------------------------------------
I've created the timestamp bug as HIVE-8746. The fix for that one is pretty
touchy and I'll do it in 0.15 I think rather than risk the 0.14 release.
I don't want to create a new write format since the old reader will read the
corrected files. I will add a flag that I can use to suppress using the split
elimination code for files with broken stripe/file indexes.
Does that sound reasonable?
