> [HS2] Enhance DriverTxnHandler.isValidTxnListState logic to include tableId
> comparison

> Key: HIVE-24796
> URL: https://issues.apache.org/jira/browse/HIVE-24796
> Project: Hive
> Issue Type: Sub-task
> Components: HiveServer2
> Reporter: Kishen Das
> Assignee: Kishen Das
> Priority: Major
>
> In HS2, after query compilation phase, we acquire lock in DriverTxnHandler.
> isValidTxnListState and later ensure there are no conflicting transactions by
> using driverContext.getTxnManager().getLatestTxnIdInConflict(); . This
> doesn't work well, if there are external entities that drop and recreate the
> table with the same name. So, we should also make sure the tableId itself is
> not changed, after lock has been acquired. This Jira is to enhance the
> DriverTxnHandler.isValidTxnListState logic to include tableId comparison.
