Wei Zheng commented on HIVE-11716:
----------------------------------
Sounds good. Now users can change the TxnManager for real. But one issue is,
initialize a TxnManager for every query might be a little slower than reusing
the same one in a session (because we will check conf every time and init a
TxnManager)
> Reading ACID table from non-acid session should raise an error

> if someone performs a delete using DbTxnManager and than starts a new session
> with DummyTxnManager, then previously successfully deleted data will show up.
> Once the logic to identify all acid tables being read is there, make sure that
> Driver.recordValidTxns() called iff there ACID tables in the query.
> We should also not allow writing to ACID table from non-acid session
