Review comment:
are these methods just moved over/consolidated?

Review comment:
block size is a per file thing in HDFS. but rarely ever set differently.
For cloud storage its all 0s. We need to see if `getDefaultBlockSize()` is an
RPC call. if so, then need to avoid this, even if it assumes things.

I am blanking now. but worth tracing why we needed these i.e any other
Hive gotchas around combine input format etc?

Review comment:
realtime is a remnant from the design motivations for MOR snapshot
queries. We might even revive it after the caching story
