      Description

      LlapDataREader is almost identical to ORC's DataREader, however the main issue the readFileData method of the latter takes a DiskRangeList instead of a BufferChunkList.

      ORC-1.6 uses a separate StripePlanner that reads RowGroups converting them to BufferChunks while in LLAP we are doing our own custom planning with DiskRanges.

      I am opening this ticket to explore moving LLAP to Stripe planning
