> 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.
