Sergey Shelukhin updated HIVE-9439:
-----------------------------------
Attachment: HIVE-9439.patch
Attaching the patch. We expect subsequent RGs to be close... not sure if it
makes sense to populate and check lastRange between different streams; would
the be expected to be close together?
> merge ORC disk ranges as we go when reading RGs
