    Description

      Currently the Acid compactor is implemented as generated MR job (CompactorMR.java).

      It could also be expressed as a Hive query that reads from a given partition and writes data back to the same partition. This will merge the deltas and 'apply' the delete events. The simplest would be to just use Insert Overwrite but that will change all ROW__IDs which we don't want.

      Need to implement this in a way that preserves ROW__IDs and creates a new base_x directory to handle Major compaction.

      Minor compaction will be investigated separately.
