    [CARBONDATA-246] compaction is wrong in case if last segment is not assigned to an executor.

    PROBLEM:
   
    if during compaction of 4 loads, for any executor if only first 3 loads task is assigned then the col cardinality calculation based on the last segment info will become wrong.
   
    in this case the cardinality will go wrong for that executor.
   
    Solution :
   
    Pass the segment properties info from the driver using the last segment.
