Description

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.
