Sergey Shelukhin commented on HIVE-10161:
-----------------------------------------
It's not hardcoded, it's specified in file footer. Either the read is
corrupted, or this seems to go against the contract of ORC file (that all
compression buffers are limited to this size uncompressed). [~prasanth_j] can
you comment?
