Eugene Koifman commented on HIVE-11716:
---------------------------------------
I think it should only initialized if it is not already set or if there is
explicit "set hive.txn.manager..." command. In the later case, the previous
instance must be shutdown first.
> 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
