    Description

      Currently the LLAP branch has refactored the ORC code to have different code paths depending on whether the data is coming from the cache or a FileSystem.

      We need to introduce a concept of a DataSource that is responsible for getting the necessary bytes regardless of whether they are coming from a FileSystem, in memory cache, or both.
