Sergey Shelukhin commented on HIVE-6060:
----------------------------------------

I am doing a review slowly, got about 40% of the way thru so far. Note that I 
am not familiar with surrounding code so comments on RB are mostly low level.
Is there a design doc somewhere that would describe the changes?
Do I understand correctly that "originals" are files from current table 
structure, and that the patch requires filesystem structure change?

> We need to define some new APIs for how Hive interacts with the file formats 
> since it needs to be much richer than the current RecordReader and 
> RecordWriter.
