Aron Hamvas commented on HIVE-22341:
------------------------------------
Is this about the HMS DB operations? Like, setting the txn state to aborted and
deleting the records from HIVE_LOCKS based on txnid?
If that is the case, then I am pretty sure HMS is doing that in a single
transaction. The logic itself is in the private method 'abortTxns', and there
are no guarantees *inside* this method that it is done in a single transaction,
but every caller of this method passes an SQL Connection object with
auto-commit set to false, and there there is no commit() call in the connection
inside the 'abortTxns' method.
> abortTxns statements should be executed in a single transaction

> Logic in `abortTxns` should be executed in a single transaction, rather than
> multiple ones. Otherwise, if you restart HMS between txn abort and the lock
> deletion, we end up with orphaned locks.
