> Currently getAcidState() makes 3 calls into the FS api which could be answered by making
a single recursive listDir call and reusing the same data to check for isRawFormat() and isValidBase().
> All delta operations for a single partition can go against a single listed directory
snapshot instead of interacting with the NameNode or ObjectStore within the inner loop.
