Sergey Shelukhin resolved HIVE-19934.
-------------------------------------
       Resolution: Fixed
    Fix Version/s:     (was: 4.0.0)
                   txnstats

Added a simple test for variations of insert and delete.
Partially covered by other new tests, this just focuses on various combinations of rows affected and all the operations.. seems like it works correctly for all cases.

> ACID table UPDATE/DELETE 
> 1. should accurately compute table stats (if started from
> accurate stats status and with hive.stats.autogather or hive.starts.column.autogather
> being true) and keep "true" for "BASIC_STATS" of COLUMN_STATS_ACCURATE.
> 2. should turn off COLUMN_STATS (or turn to "false").
