Owen O'Malley updated HIVE-8732: -------------------------------- Attachment: HIVE-8732.patch Here is what I had in mind. This patch: * adds an optional writerVersion to the postscript, which tracks the bugs fixed in the writer * uses the flag to disable predicate pushdown in split calculation, which seems to be the only usage of the stripe statistics within Hive * tags any new files with having HIVE_8732 fixed * adds tests for the merge where the original range is larger. You're right that the Orc reader don't block reading future versions, but I think this is a little cleaner. Furthermore, if someone back ports this to Hive 0.13 they can do this without claiming to be writing a Hive 0.14 file.
