    Description

      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.
