[~teddy.choi] left one small comment on RB, can be fixed on commit. Although I guess some test fix will be needed for the above failures also.
Looks like a NPE

> LLAP uses a completely separate read path in ORC to allow for caching and parallelization of reads and processing. This path does not support ACID. As far as I remember ACID logic is embedded inside ORC format; we need to refactor it to be on top of some interface, if practical; or just port it to LLAP read path.
> Another consideration is how the logic will work with cache. The cache is currently low-level (CB-level in ORC), so we could just use it to read bases and deltas (deltas should be cached with higher priority) and merge as usual. We could also cache merged representation in future.
