Sergey Shelukhin updated HIVE-11595:
------------------------------------
Description: If ORC footer is read from cache, we want to parse it without
having the reader, opening a file, etc. I thought it would be as simple as
protobuf parseFrom bytes, but apparently there's bunch of stuff going on there.
It needs to be accessible via something like parseFrom(ByteBuffer), or similar.
