      Description

      Because we are using the same hiveConf and we are currently using ColumnProjectionUtils.appendReadColumnIDs ColumnProjectionUtils.appendReadColumnNames to append needed column ids and names for a table, lists of needed column ids and names can have unnecessary columns.

      Also, for a join operation, TableScanOperators for both tables are sharing the same hiveConf and they may need to set table-specific properties.
