Owen O'Malley updated HIVE-12159:
---------------------------------
    Attachment: HIVE-12159.patch

Ok, this is rebase to master, which took a fair amount of work because of 
HIVE-13523. In particular, I've removed the DataReaderFactory and 
MetadataReaderFactory, because they weren't providing any abstraction. They 
were baked into ReaderImpl with final fields. I also merged DataReader and 
MetadataReader so that RecordReaderImpl just has a single connection to HDFS 
open rather than two.
