Owen O'Malley commented on HIVE-11259:
--------------------------------------
You need to remove the dependence between Reader and ReaderImpl and the
EncodedReader and EncodedReaderImpl. I'd suggest adding passing a factory
object into the OrcFile.ReaderOptions that can control the implementation of
the TreeReaders and RecordReader.
Basically, the goal is to make it so that LLAP can pass in a factory object
that lets it control the behavior of the RecordReader and TreeReaders without
making the ORC reader depend on LLAP.
