---------------------------------------

seem reasonable.  [~sankarh]?

> ValidWriteIdList config should be defined on tables which has to collect 
> stats after insert.

> In HIVE-18192 , per table write ID was introduced where snapshot isolation is 
> built using ValidWriteIdList on tables which are read with in a txn. 
> ReadEntity list is referred to decide which table is read within a txn.
> For insert operation, table will be found only in WriteEntity, but the table 
> is read to collect stats.
> So, it is needed to build the ValidWriteIdList for tables/partition part of 
> WriteEntity as well.
